This knife is hand made from 3/16" ATS-34 Stainless Steel..... a stainless steel almost identical to 154CM. The knife has a full tang and is tapered over the full length of the knife. The blade has been sharpened using a convex, or Moran Grind. The extra steel throughout the whole knife gives the user the feeling of real substance when the knife is in hand. The 7 1/4" knife's feel is further enhanced by the extra weight of the second set of bolsters at the rear of the handle. All of this combines to put the balance point just 'behind' the center of the knifes length. The five finger depressions offer a maximum sense of control and especially so, when you let your index finger jump over the front bolster and place your thumb on top of the blade. This knife was made for work! It carries the makers mark on the blade which has been hand rubbed to a semi gloss finish. The handle slabs are made of care free wine colored diamond wood with black micarta spacers between them and the nickle-silver bolsters that are hand fashioned and polished to a high gloss. The blade was heat treated by Paterson in his own shop using Evenheats 18" deep electric knife kiln. It was heated to 1950 degrees F and held for 30 minutes. The makers reports he likes to put his blades in the kiln when the temperature is about 1200 degrees. At the end of the 30 minute soak at temperature, the blade was removed and quenched in 200 degree olive oil. The stainless was then tempered by soaking it at 936 degrees F for one hour. That was followed by air cooling the blade to room temperature. This process results in what the maker feels is the near perfect R/C of 58-59..... Not too hard for sharpening and doesn't chip, and hard enough to hold a premium edge you'd want any working knife to hold. A leather sheath is being made for this knife at this time.
