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!
