German Kinetics USA has them 3 for 66.99 now....see below: (by the way...I get nothing for being a admirer of these broadheads, wish I did :-)...thought those unfamiliar with them might enjoy the description from the site).
"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:
Ferrule 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/mm² 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 with anodizing in 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. Blade
Material: X90CrMoV18
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!! 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. No other manufacturer offers this blade strength!! Prior to this process the blades are bead-blasted and vibratory ground.
The blades are precisely tempered to 55-57 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.
The treatment of the blades is made by a specialized company for high-quality industrial knives in Germany’s "knifemaker capital city" SOLINGEN. Screws
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.
Three broadheads per pack.
