I have had a pocket knife since I was a young boy in Northeast Texas. I fondly remember the quite days when my Daddy and Grand Daddy taught me how to sharpen a knife using a small 3 1/2 inch whetstone. My every-day-carry is a Buck 301 (USA made). A great, old time knife with excellent stainless steel blades. I just finished sharpening it to "shave-the-hair" sharpness using a Dan's Soft Arkansas Whetstone. I use it from opening letters to whittling walking sticks. I have my Father's pocket knife which has to be 60 plus years old. It is a Craftsman which I believe was made by Case. It has a carbon steel based blade. While holding a great edge and easy to sharpen, it is prone to rust and staining (patina). I have a number of other knives: Case Trapper with Chrome Vanadium blades/Amber Bone handle Case Canoe with Chrome Vanadium blades/Amber Bone handle Case Medium Stockman with Chrome Vanadium blades/Red Bone handle Buck 371 (excellent fit and finish/China version of the Buck 301) with Stainless Steel blades/wood handle Buck 389 with Stainless Steel blades/wood handle The Case Trapper and the Case Canoe are my Sunday going-to-church knifes. No whittling. They are very nice, quality knives. Do you have/carry a pocket knife? Use for what? How do you sharpen? I plan to teach my Granddaughter how to whittle, sharpen a knife, and play Mumblety-peg.
