SilverFlame broadheads consistently pursue the principle of the single or two-bladed broadhead as one has known them for thousands of years.
My goal is to produce a broadhead with which the bowhunter does not even need to concern himself with the ability to perform, if in place of a skinny deer suddenly a massive hog comes into sight and/or if the impact angle of the arrow by a sudden movement of the game is no longer ideal.
Here by any means the effectiveness is not to be questioned regarding by multi-bladed broadheads. Up to certain game strengths and outside of critical hunting situations, three and multi-bladed broadheads have quite their target-ballistic validation. Innumerable successful hunts confirm this fact.
Unfortunately there is however certain critical hunting situations, in which always everything does not work according to plan and some crucial inches of penetration, are lacking, in order to cause a fast humane death of the game. A multiplicity of cutting blades does not help in these instances, if the vital zone is not reached or is not completely penetrated. In its wake a hurt creature remains, with perhaps some unwanted public resentment, not to mention a very disappointed hunter.
Please consider that a two-blader has to break the bone due to the straight aligning blade arrangement only once, in order to produce a gap for the arrow shaft. A three-blader has to do this repeatedly three times.
We do not regard broadheads as throw-away articles !!
They should be a high-quality, dependable tool, same as the bow, the arrows or the hunting knife!!
SilverFlame Broadheads had been introduced in summer 2003. Since that time they performed flawlessly up to the toughest game strength.
From the amazing game of the northern hemisphere up to the largest big game on the Dark Continent, inclusive African elephant, serious bowhunters as well as experienced hunting guides all over the planet confidentially rely on the performance of the SilverFlame Broadheads.
A non-gimmick, ingenious construction, made from high-grade materials at lowest tolerances and carefully honed cutting edges constitutes an incomparable level of quality.
SilverFlame broadheads incorporate an amount of structural integrity that invariably one searches in vain with most other manufacturers. Only an ingenious construction, based on solid design, combined with the correct materials, constitutes a first-class product.
The facts speak for themselves:
Material: AlZnMgCu1,5 F53
Internationally better known under the ASTM designation 7075 T6
This high-strength aluminum alloy contains a tensile strength of 540 N/mm which is approx. 1.5 times stronger than average construction steel and is used in many cases, where high-strength, but light materials are needed.
Aircraft engineers as well as the top technical designers of world class racing bicycles, appreciate the advantages derived from this material.
The ferrules are manufactured in a CNC process. They are in turn ground in a vibratory in order to remove even the finest remaining burr particles. The surface finish will be done by hardcoat anodizing Mil-Spec Type III the color black silk matt.
As technical characteristic the ferrules show a "round butt", thus a radius to the arrow shaft. Consequently the use of conical washers (U.B.A.R.'s etc.) is eliminated, thus minimizing retraction resistance of the arrow from the practice target.
The thickest portion of the ferrule has a diameter of 8.5mm (> 21/64") and is thus somewhat thicker than most of today's more common carbon hunting shafts, with diameters amounting to somewhat less than 8mm (5/16").
The transition between the main body and the shank, which get screwed together with the thread into the insert, was turned not on 90, but provided with a small radius by 0.5mm. This radius effectively provides two distinct advantages, an increased bending stability and allows for the self-centering in the insert of the arrow shaft.
Internationally also known under the ASTM designation 440 B. You will recognize that alloy from high-grade hunting knives as well
In actual bowhunting practice you will appreciate the first-class combination of edge-retention and easy resharpening.
The blades are a ready to use right out of the box! That's right, both the assembled broadheads as well as the replacement blades are razor sharp and will take the hair off your arm effortlessly.
Handle with the utmost precaution!!
SAFETY FIRST AND ALWAYS!!
A CNC-Laser cuts the blades from a tool steel board. The thickness of 1.80mm (.071") and the grinding of the cutting edges are made in a CNC wet-grinding process to preserve the hardness of the steel. The blade of the SilverFlame 100gr. and XL125gr. comes 1.40mm (0.055")
No other manufacturer offers this blade quality!!
Prior to this process the blades are bead-blasted and vibratory ground.
The blades are precisely tempered to 57 HRC.
In order to ensure a homogenous molecular structure of the steel, the blades are then subzero quenched in a special cooling chamber.
The final process in achieving razor sharpness is accomplished by de-burring of the edges on a wheel containing elephant leather and a special polish paste.
The rear blade (trailing edge) is not sharpened at the factory. This feature serves the intended purpose, as well as the rounded off ferrule, an easier arrow retraction.
All blades have a cutting diameter of 1-1/8" to meet all relevant hunting laws and regulations worldwide. SilverFlames XL come with a cutting width of 1.5" for maximum damage.
The treatment of the blades is made by a specialized company for high-quality industrial knives in Germany's "knifemaker capital city" SOLINGEN.
Inform yourself also under geometry, what constitutes an effective and ingenious construction.
The two screws used for blade attachment (M2.5 x 5) are made from stainless steel (V2A).
The screw head has a TORX drive (T6), which is considerably more durable than a hexagonal or slot drive.
The screws are not standard parts. They are manufactured exclusively for the SilverFlame Broadheads. The radius of the screw head corresponds to that of the ferrule.
Consistently CONVEX !!!
If one regards the blade shape of today's broadheads axially for impulse direction, especially those broadheads designed to cut-on-contact, then there are three different basic geometries: Convex, concave and V-style.
More than 90% of all broadhead blades possess a V-style, thus a straight cut. This is due to economical reasons, since a straight cut can be sharpened most simply and thus most cheaply industrially.
The reason, why the SilverFlame Broadheads come with a convex geometry, is because of the vast superiority of this shape when compared the two previously mentioned, when it comes to penetrating hard material (bone), based on the following reasoning:
As long as the broadhead meets no considerable resistance, geometry does not play a large role. If it applies to press however hard material apart or blow up, the V-shaped and even more the concave blade will show a lack of performance comparing to the convex blade, since first two always have full blade contact with the material, while the convex point already breaks and presses the bones apart at its tangents. Thus only that which was not cut at the tangent, slides over the remaining length of the cutting surface.
There exists certain principles/dynamics which are accepted universally as they apply to the performance of any cutting edge.
For example, imagine, you want to split a wooden stump (log) and have one wedge, each containing the three mentioned geometries for the task at hand. With the concave wedge penetration will be slight as it seizes during the initial forces upon contact.
Furthermore, you will discover the V-shaped wedge clearly outperforms the concave wedge in penetration.
The convex wedge will even prove far superior to both the previously mentioned shapes. This occurs due to the gap created, without regard to the wedge thickness, but will rather clearly continue to open. Inquire with your butcher regarding this principle, ask him which blade geometry creates the optimum bone splitting ability.
The SilverFlame Broadheads incorporate not only a convex blade, but also a convex ferrule tip. The outermost point is far less sensitive with this geometry than with a V-shaped one or a concave blade.
Blade length (Cutting surface)
The decade-old opinion about the penetrative superiority of a long and narrow blade is physically correct but must be related however concerning the structural integrity of a practicable broadhead.
The accepted length width relationship of 3 : 1, which was publicized at that time by people such as Howard Hill, has quite its authorization, as long as one regards only the narrow blade angle.
The large disadvantage of such a long blade is clearly the "elastically deformation" or "Flexing".
So some bowhunters often have been dismayed at the resulting unsatisfactory penetration of their hunting arrows, although this, when late investigation, was perfectly intact including the broadhead?
The reason for the most part high amounts of energy and momentum, which is used by a very long broadhead at hard hits during the flexible deformation. Also the material choice for the blade is important here. Some manufacturers of very long blades use spring steel, which naturally still supports the flexing effect.
Especially on penetrating harder materials (bones) longer blades (broadheads) have to deal with more friction than shorter ones, too.
An efficient blade construction consists of an adequate combination of cutting length and resistance ability against the flexing, thus as a high amount of the arrow's force for the forward movement (impulse direction) through the game's body as possible will remain intact.
We are most confident that with the SilverFlame Broadheads, we have indeed developed an outstanding and effective combination.
Advice for resharpening:
If one asks an experienced bowhunter for the most important aspects of successful bowhunting, the answer will be:
"Shot placement and a super-sharp broadhead!"
The anatomically correct placement of the hunting arrow is a job we cannot do for you, but the excellent sharpness of our broadheads we guarantee!!
So that you bring your broadheads even after multiple use, to the practice target or after hunting back to the necessary cutting performance, some important things should be considered when resharpening.
The blades of the SilverFlame Broadheads are ground at an angle of 38, thus 19 per blade side.
In order to bring it back to razor sharpness, it should be done at an angle of 40 (20 per side) or a larger angle.
Contrary to most other broadheads, which typically have a v-shaped blade, SilverFlame Broadheads can be resharpened troublefree, without the sharpening device touching the ferrule.
An angle of 40 is proved to be an ideal combination of outstanding sharpness and edge retention.
Surely you can resharpen also in a larger angle, if you want to optimize the blade on edge retention.
All useful sharpening devices offer an adjustable and to all reproducible sharpening angle.
Most sharpening devices of well-known manufacturers such as WICKED EDGE, LANSKY, DMT, GATCO, SPYDERCO, RAZOREDGE SYSTEMS and identically constructed models are suitable very well, in order to help with expert hand a used SilverFlame blade to a hunting adequate sharpness.
A usefully sharpened blade shaves the hair of the forearm effortlessly and needs an adequate amount of caution and respect in handling.
We do not recommend the usage of so-called "Quick-Sharpeners", as one typically finds them in discount department stores, household business and even with some broadhead manufacturers.
These "pull-through-sharpeners" consist mostly of two tungsten carbide or ceramic(s) panels, which oppose one another other fixed in a certain angle. This angle corresponds only in the rarest cases to that of the blade, which you want to sharpen.
This tool works thus metal chip removing and produces a thin, first allegedly sharp burr on the very edge, that however will lay aside or break away completely at the first contact with tough materials.
These devices are an absolute makeshift device and its result has nothing to do with a professional sharpening. You should by the way also save your high-grade hunting knife from this torture.
