I carry an Ontario SP2 Pilot Survival knife when hiking and backpacking. While it's kind of heavy for those situations I use it as my cathole digger as well as a survival knife/mountain lion defense tool.

Yes, digging with it can be considered as abuse but... it's not expensive and the 20-year usage hasn't really damaged it in ways that couldn't be fixed with some time on a diamond stone. (I carry a small diamond rod in my pack to use when needed or when waiting out a rainstorm.) The paint is missing toward the point but the edge has been restored to very, very sharp.

It's a tool. I have many other much prettier knives that don't get out in the sunshine much.
