I'm looking to upgrade my round knife and my research led me to some vintage leather tools. I came across a Theo Harrington for sale that looks to be in a decent condition. I know they're pretty old but seem to have a good reputation for quality steel. Before finalizing my purchase, I wanted to see if anyone here has any experience using one. How do they hold an edge compared to a modern knife? Are they comfortable to use? I've been using a basic head knife for a while and want something that will last and hold a good edge for a long time. I'd appreciate any thoughts or advice!
