This is Buck's standard blade material because it approaches the wear resistance of high carbon alloys while delivering the corrosion resistance of chromium stainless steels. Add our exclusive heat-treat process and you have a very user-friendly combination of superior corrosion resistance with excellent strength for wear resistance and durability. You also have a blade that is easy to resharpen. For best performance we harden to a Rockwell hardness of Rc 58.
Over the years like 40 I have purchased Buck as well as many others.BUCK IS A GREAT TOOL.
I Received my custom 503 with 420HC polished blade and cherry-wood handles for my sixteenth birthday and I'm very satisfied with the quality of the knife. The knife was delivered about six weeks after ordered. The engraved blade was polished to perfection and the handle was stained consistently throughout. It Seams pretty sturdy and is just the right size for everyday pocket carrying. overall it's a quality knife that will last generations and makes a great gift for all ages.
I have had my 503 for at least 40 YRS. It is my constant companion. It has done everything from opening the mail to opening Xmas presents for my children & Grandchildren to doing heavy jobs. It is everything a could ever want in a knife.
I have been using a Buck knife for over 40 years. They are the best knife on the market and I have tried others. The only reason I have had to replace one is because I lose them. Other than that, they will last forever.
I know I have had this knife for at least 30 years. I carry it in a small case that my belt passes through. It is always sharp. Only needs a little sharpening when I do something dumb. Use the back of the knife for opening packages and the blade for everything else.
