If you’re an old timey pocket knife fan, how about checking out the Cudeman Classic slip joint in Olive wood. It was invented well before pocket knifves had clips, I think. And even if it wasn’t, it still is pretty cool. The knife was manufactured in Spain by fine artisans, I think, and features a 420 stainless steel blade made for cutting stuff. If you think this knife is something you might need in your life, you can buy it off Amazon, where I did. Looks like the price went up by $10 though.
