I keep my Mercator K55K in my wallet because it's slim like a pancake. I guess any Douk-Douk- like knife is a great choice if this is a strong factor. You have to like the retro-look though.
Usually take one out of the pile of cheap junk I get over the years. Seems like every year I buy one the next year Im buying another. That said for cheap knives I buy im partial to Kershaws
I’ve carried a mini griptilian for several years it’s been sent in once for sharpening and a tune up I have several other benchmade pocket knives but keep going back.
i have a leatherman sideclip. from what i understand it is a fairly rare leatherman and worth some money. It is thin enough to fit in my pocket comfortably but still has the standard leatherman tools.
Dieter CQD Mark II - first gen model before Blackhawk started producing them.
My brother went through Duane's class and snagged one. He gave it to me before his first trip to the sandbox as a high school graduation present, absolutely priceless to me.
I have a griptillian for back up when the clip gets bent on my benmade 940. The griptillian is too bulky clipped in my pocket. Really my only complaint but to me a big one being its there every day. Ive had my 940 for about 7 years now. To me its the perfect EDC.
