Handcrafted in the U.S.A., this classic American Case Sowbelly is about 3 7/8 inches long (folded/closed) and weighs approximately 3.6 ounces. The handle is Yellow Delrin Synthetic with an Oval Nickel Silver Case Inlay shield. The bolsters are highly polished Nickel Silver. This knife utilizes a 2 3/4" Clip blade, 2 1/4" Sheepfoot Coping blade and 2 1/8" Spey blade. Stamped with pattern number TB3339 CS, the blade material is Carbon Steel. Note: Carbon Steel is generally harder than stainless steel, this allows the blade to hold a sharper edge, longer. However, Carbon Steel will corrode/rust if it's not cleaned and oiled regularly.
