NOTICE!
		I've made a new layout for the tactical knife descriptions, seen 
			on this page. I've separated the 
			components, briefly describing them in individual boxes. In those boxes 
			are links to dedicated pages describing everything about the part, 
			component, or accessory. The pages are substantial, and offer the 
			history, operation, materials, use, mounting, and care of each 
			accessory.

		The Knife
		
			- Size: Greatest length overall max: 8.7" (22.1 cm), 
			Greatest length at handle: 5.0" (12.7 cm), Blade Length at outside 
			(convex) cutting edge: 
			5.25" (13.3 cm), Blade Length at inside (concave) cutting edge: 
			6" (15.24 cm), Thickness: 0.275" (7.0 mm)
 
			- Weight: 12.9 oz. (366 grams)
 
			- Blade: 440C High Chromium Martensitic Stainless Tool Steel, Hardened and Tempered, T4 Specialty Cryogenically treated to Rockwell C59, proprietary surface oxide treatment "Ghost Slate."
 
			- Type/Purpose/Origin: In a unique design, the 
			combination of a double-edged karambit sickle-type blade and a 
			finger ring, push-punch dagger handle come together for a serious defensive and 
			tactical knife, with keen cutting potential and serious presence. 
			The knife is named "Drepan" which is the Old English word meaning
			to strike down or to kill. The karambit blade 
			design has its 
			history in ancient harvesting, and has developed into a common knife 
			profile and design. This is one of the more aggressive patterns, 
			with double edges on the blade.
 
			- Blade Steel Alloy: The Drepan blade is a well-proven standard, the hypereutectoid, high alloy martensitic 
				stainless tool steel, 440C. This is my most 
			requested steel for a reason. When properly treated, it's a 
			dependable, reliable workhorse of extremely high corrosion 
			resistance, good toughness and high wear resistance. The extremely 
			high chromium of 440C along with the high carbon and moderate 
			molybdenum results in profuse chromium carbides, increasing 
			corrosion resistance as well as wear resistance. There is a reason 
			that 440C is the steel that all other stainless tool steels are 
			compared to. This steel is suitable for marine saltwater use.
 
			- Heat Treatment: To bring this steel to its 
			zenith, I used my proprietary T4 deep cryogenic process in heat 
			treating this blade; it's a highly detailed, extremely sophisticated 
			process that takes 36 individual steps and takes over a week long. 
			The result of this is an incredibly wear-resistant blade that has 
			extremely high carbide development, fine grain, and extremely high 
			toughness. Asperity is reduced; the microstructure development is 
			superior to any other typical handmade knife, and far above any 
			factory or manufactured knife. This is, simply put, 440C martensitic 
			stainless steel at its very finest advanced condition. The result is a 
			very tough, hard, 
				wear-resistant stainless steel. This is a testament to my 
				determination to make the very best knives, steels, treatments 
				and kits in the modern world. I know of no one else who has 
				advanced the treatment to this level; it's unheard of in the 
				metals and knifemaking field.   This is, simply 
				put, 440C at its very finest advanced condition.
			
			More about the heat treating designation.
 
			- Blade Design and Geometry: The first striking 
			thing about this blade is that it's double edged. The exterior 
			convex edge has an abrupt hollow grind that I accomplished with a 3" 
			diameter wheel, a very difficult grind to do well. This leaves 
			plenty of thickness in the central spine to support the aggressive, 
			slender tip, and gives good mass to the blade overall, stiffening 
			the cross-section of the blade. The concave grind is a taper grind, 
			smooth and even and sweeping about a radical curve of approximately 
			150 degrees. Though hard to define, this creates a total cutting edge length 
			of about 6". Combine this with the convex edge, and this small 
			blade has over 10" of combined cutting edge! The blade base has a very 
			large quillon to protect the hand from the edge, giving more stiffness 
			and control with a rounded, contoured surface that is not abrasive 
			to the hand. 
 
			- Blade Finish: The blade is finished in my flat, 
				dark "Shadow" line of 
				counterterrorism, rescue, and tactical knife finishes. Answering 
				the request for completely subdued and non-reflective 
				surfaces, I developed the Shadow Line with my Ghost 
				Slate finish. This means darkening in a permanent 
				fashion the stainless steel of the knife, to color-compliment 
			the sheaths. Read more about 
				my Shadow Line and Ghost Slate finish on my 
				Counterterrorism Knives page
				at this bookmark.
 
			- Bolsters: I bolstered the knife in my zero-care 
			304 austenitic stainless steel standard, for the most reliable, 
			tough, and durable material. This is the same steel that stainless 
			and marine-grade fasteners are made of; it's completely care-free. 
			The bolsters are dovetailed to support the handle material and offer 
			a thicker grip for the hand. They are attached with multiple 
			zero-clearance peened pins for permanence.
 
			- Handle: The handle I chose for this knife is 
			orange and black patterned G10 fiberglass/epoxy laminate composite. 
			This is extremely tough material, and should last indefinitely with little 
			care. The finish is media-blasted for grip improvement, and the 
			handle scales are secured with two stainless steel pins. The handle 
			scales and bolsters are contoured together for comfort and grip 
			security. The spine of the knife is at full thickness in the handle, 
			which has been internally milled for weight reduction, and is fully fileworked 
			with a bold sunrise pattern for handmade distinction. The handle has a 
			"talon," a feature proven to be useful in my other tactical, combat, 
			and counterterrorism knives, for breaching, glass breaking, and 
			defense in hammer grip style. One of the most unusual aspects of 
			this knife is the oval finger ring incorporated into the design. 
 
			- Balance and Feel: For a knife of this design, 
			balance is hard to define, but the weight balance is right at the 
			"bridge" where the fingers are closest in standard grip style 
			between the finger ring and the middle finger position. But 
			what is standard in such an unusual design? With the forefinger 
			(index finger) through the ring, the talon on the knife handle is at the butt 
			of the hand, making for a good hammer-fist grip that is solid and 
			secure; the thumb lays atop the the outside of the finger ring which offers good 
			width to apply pressure and stability. This seems logical for a 
			punching motion. In reverse grip, the thumb lays atop the talon and 
			the little finger is in the ring, and the handle is swallowed or 
			nested deeply in the palm. In this grip a 
			sweeping, scooping motion employs the radical inside curve of the 
			cutting edge. Since there will be many more grip styles in this 
			unusual blade, the owner will surely have his favorites. 
 
			- This is an advanced blade with applications of a 
			defensive weapon in close quarters combat, 
			or a tool that could not easily be defeated or guarded against, since 
			it's basically all edges and an invasive point. It's also great for 
			harvesting rice and grain, which is the original purpose of the 
			karambit blade, historically.

		The Sheath
		The Standard Sheath
			
			- Weight: 6.3 oz. (179 grams)
 
			- Materials: 9-10 oz. Leather Shoulder, Stainless 
			Steel Fasteners, Nylon Thread
 
			- Description: A 
			traditional sheath with an easy unsheathing ability, I made this one 
			in heavy leather shoulder, with a tri-weave 
			basketweave tooling pattern. I dyed it in traditional black and stitched it with heavy nylon thread. Note that
			this sheath 
			accommodates only a narrow belt, approximately 1", so the knife 
			can be oriented in a mostly vertical position (as much as can be described, since the knife 
			has such a curved and radically-shaped blade. Again, the triple-row 
			stitching in the belt loop will accommodate a 1" (2.5 cm) wide 
			belt. This is an unusual sheath, and care must be taken in using it, 
			since it has NO retention method. Due to the 
			curvature of the blade, the knife must be "rolled" out of the sheath. 
			It will make more sense when the owner uses it. This sheath then 
			allows the fastest unsheathing possible, simply "rolling" the knife 
			up out of the slip. The sheath is rounded, contoured, smoothed, and 
			sealed with lacquer for longevity, double row stitched at the welts 
			and reinforced at the critical mouth points with stainless steel 
			fasteners.
 
			- Simply put: This is a vertical sheath with a 
			fast, smooth, and easy unsheathing, with a traditional fit and no retention 
			hassle.
