New DC Finish Apha Dog 6 in INFI (Last One)..(More about INFI Steel below)..

This is a serious Military Type knife made of a proprietary super steel INFI!!!. All the edges are eased and the normal SYKCO handle (see below). 

Package includes taco style kydex sheath. I made the sheath from .080 SuperCam . The eyelets are set for a large Tek Lok or Molle Lok (included). The Tek Lok can mount in the vertical, scout and modified scout positions as well as left or right hand pull.

This sheath was formed and fitted to this exact knife. There is no rattle and a smooth pull with thumb ramp. 

All upgrades and add ones at normal pricing.

INFI is a proprietary steel and heat-treat protocol developed by Busse Combat Knife Co. It is ONLY available through Busse Combat.

Some facts and info about INFI.




Although hardened INFI knives are 58-60 Rc we have yet been able to chip an edge. The edge can be dented or misaligned but its high level of malleability at such high hardness has never been duplicated by any other steel that we are aware of or have tested.




In one of our performance tests, we bend a Battle Mistress 35 degrees in a vise and it springs back to true. Why would we do this? What does it prove? What is the benefit to the customer? Not only does this test demonstrate the enormous toughness and lateral strength of an INFI blade but, because our hardness is homogenous and not differential, it demonstrates the amount of lateral strength and "spring" of INFI all the way to the edge. That means that edge of the blade will possess this same toughness. INFI is the only knife steel ever tested that has achieved such high levels of lateral strength with a homogenous hardness of 58 - 60 Rc. No other steel has even neared this performance level.


Edge Retention


Many so-called knife experts have heralded the "wear resistance" of a steel as the key to edge retention. This may very well be true if a knife is designed and intended for the cutting of soft materials ONLY. However, we have never inspected a dull knife and found the edge to be perfectly smoothed away, like a ball bearing. Instead what we find are microscopic chips where the edge has broken or chipped away like glass after having impacted against bone, gravel, or other hard surfaces. This micro chipping dictates that the edge be reground during the resharpening process, which will ultimately lead to a thicker edge and a radical change in overall blade shape. Steels with high wear resistance normally score fairly low in shock resistance, lateral strength, and overall toughness. INFI scores very high in ALL of these categories.




INFI's high level of chip resistance also makes it the easiest steel to resharpen by hand that we have ever encountered.  One of the great features of INFI is that simply stropping away from the edge (the way a barber strops a straight edged razor) on a ceramic stick is basically all that is required to resharpen INFI. Since you're not chipping steel off the edge there is no need to grind any steel away. This feature of INFI will, likewise, allow you to keep the same overall profile of the knife for a much greater period of time.


How does INFI compare to other steels?


Simple question, complex answer. INFI represents what we have always dreamed of in a knife steel. Tougher, by an enormous margin, than any other steel we've ever tested. It has unparalleled edge holding under high impact and in cutting tests, and shock resistance that begs you to "bring it on". INFI has an ease of re-sharpening that you have to see to believe and higher levels of lateral strength at high hardness than have ever been achieved by any other steel. We have published our test results and our testing methodology. We have video taped all of these tests and play the video at the knife shows we attend. More importantly, we have duplicated these performance tests in "LIVE" demonstrations at many trade shows throughout the United States. We encourage all manufacturers to put their products through our tests and to publish their results. If you want to know how another maker's knife will compare to a Busse Combat knife, ask the other maker to duplicate our tests in a "live" demo.


Is INFI stainless?


INFI is technically not supposed to be, however, INFI has demonstrated very high levels of stain resistance in many different climates. Uncoated blades have been tested for years in Alaska and have made their way into the wilds of British Columbia, the High Sierras and tropical rain forests. No rust in Alaska or British Columbia! No rust in the High Sierras, even when exposed to great quantities of blood and left in the wet grass overnight. The tropical rain forest, which has been known to rust plastic (just kidding), did offer the toughest of the environmental exposures and a light speckling of surface oxidation did occur but was easily removed in the field with a hand rubbing of sand and water. No deep pitting was reported. When compared to other cutlery steels in salt spray tests, INFI faired better than ATS-34 and D-2. Although all three grades exhibited surface oxidation, the INFI was not deeply pitted as was common in these other two grades. So, although INFI is not technically a stainless steel, it is certainly not a rust aggressive steel. Couple this with a minimal amount of care and you've got a fairly maintenance free knife.

With a steel like INFI it's easy to understand why we offer the toughest guarantee in the business. We guarantee against any and all unintentional MAJOR damage forever.

Resiprene C

(Think of it as an all-terrain truck tire with better chemical resistance)

Resiprene C was made famous as a handle material when it was used on the Busse Combat Basics. Respirene C handles have all the advantages of rubber handles without any of the disadvantages. They are comfortable, shock absorbing, slip resistant when wet, and provide insulation from the cold. Unlike Kraton, Resiprene C is a Non-hygroscopic material which means that it will neither "take on" or "emit" fluids. This quality not only gives them unparalleled durability but makes them extremely easy to keep clean as dirt will simply not stick to them. It is impervious to salt water, petroleum based chemicals and is much more resistant to higher and colder temps than is Kraton. Resiprene C is likewise impervious to the powerful insect repellant, DEET. It is so amazingly tough and durable that Busse stands as the only company to have ever put a Lifetime Guarantee on a rubber handle. All Scrap Yard handles are fully textured to supply a slip-resistant purchase in any grip configuration. So, whether you hold the blade in a saber grip, reverse grip, upside down grip, side grip, or whatever which way you are required to hold it for your particular application, you will be assured of having a secure hold.
