This blade is handmade from 1095 steel and 15n20. As you may know, 1095 is a traditional and sought after American high carbon steel that is prized for knife blades. It is hardened to about 57-60 on the Rockwell C scale (HRC). This blade is a serious blade that will work well for hunting and fishing. It can be easily sharpened at home or in the field, and will hold an edge very well. It is genuine layered damascus steel (not fake or imitation damascus). Blank may require additional sharpening.This billet comes hardened (heat treated) and acid etched to make the pattern visible. You may anneal (soften) the billet to make working with it easier. You would then want to harden your knife just before putting on the final edge. Total Length ; 10.00 Inches Total Width : 2.50 Inches Total Thickness : 4.00 mm
