Great thread. The exercise highlights for me that it's important to own some of these knives, even if they don't make the cut for daily use.
I'm having a heck of a time picking 5 *knives*. I'll list 5 patterns that I think everybody should have at least one of, along with my personal pick of "most desired by me" within that category. Pics of some of them follow.
1) Bowie Style Fixed Blade - This includes the Ka-bar/Mk II but also all of the various hunting knives made with the bowie style blade. Eventually, I'd like to get a pre-War Marbles or Western. Till then, I have my grandfather's cheap (most likely Japanese made) post war knife. Picture below.
2) Clip Point Slip Joint - Stockmen, trappers, peanuts, Barlows... there's ton to choose from. I can't pick a favorite in this list because it's by far my least favorite blade style. I'm keeping my eye open for a US made Schrade 123OT single blade Pioneer in 1095. That would be my top pick in this class.
3) Spear Point Slip Joint - Scout knives, Electrician's knives (TL-29), US military "Demo" knives, cattle knives, canoes... This is, by far, my favorite slip-joint blade style. To my mind, if the stockman is the knife of the American cowboy, the spear point is the knife of the American laborer. My personal favorite is the Ulster camper. Picture below.
4) Brass Bolstered Folding Hunter - Lots of people made them and lots of them are real nice. I particularly like (covet) the 1095 Schrade LB7s and keep my eyes open for one. But there's only one first and it's the knife that gives this class the name "Buck knife" no matter who made it... The Buck 110. Mine is a 2 dot 440C version that I got in '78. Bolsters have been softened for better pocket carry. Picture below.
5) Farmers/Peasants Knives - I think of Sodbusters and knives like the Opinel as being close cousins. Simple. Utilitarian. Inexpensive. Effective. My pick here is the Opinel #8. It's an easy knife to dismiss due to the price but once you own one and beat on it for a while, I found it's impossible to ignore. It's just that effective. Picture below.
