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.
This blade is full bellied with a strong, thick point for heavier tasks. It can also be used as a general work knife. The top of the blade drops down toward the tip, which minimizes accidental puncturing while skinning. The drop point blade is strong and very versatile.
For just a small pocket knife, this is by far the toughest, best folding knife I have personally ever owned. And I've owned many.Amazing Solid construction, A blade that can take abuse and hold an edge. But easy to sharpen. I actually own two of the 503's.I bought the second as a backup. in case I should lose my first. I say lose because I have little fear of breakage, Or it turning to junk like other folders I've owned over the years.Bottom line.OUTSTANDING!
The 503 is the BEST knife you can fit in your pocket. Very strong. Very sharp. Very well made. Elegant and classy, yet tough and rugged. It locks open very strong, feels like a fixed-blade knife. Fits the hand perfectly. When opened and locked, it can do ANY job you would ever expect to do with a cutting tool. There is no better folding knife.
My first one I got was 30 years ago. Just bought another one today. Nothing wrong with the first one but needed one in my tool box. So now the new one resides in my pocket. Can't be without it. Great pocket knife. Just the right size.
I owned my 503 for a little over a year. Carried it in my pocket everyday, did what it was intended to do and had no complaints. Until I was cutting through some plastic zip ties on a dog kennel and the tip of the blade broke off clean. I must have gotten a knife with a weak blade or some manufacturing defect, but regardless I will not be satisfied unless it is replaced.
