I couldn't possibly pick a favorite. I haven't counted for a while, but I probably have about 120 knives at this point and would consider even the least expensive of them to be of reasonably good quality, having moved out those that were "not so much", those that didn't appeal or seem useful to me, some that were just kinda meh, and even a number that were high quality and liked, but just sat and were occasionally fondled as they were too pretty to use.
My
current favorites are my two Spartan Harsey Folders, bought within a couple months of each other, the first a brand new, very pretty Northwest edition and the second a plain Jane, bought to be a work user. I'm just amazed by how smooth and what great cutters these two are and how they feel like they were custom made to lock into my hand.
Again, I could pick any number of knives as favorites from my CRKs, RHKs, Shiros, Cheburkovs, even BMKs, Spydies, or several other makers depending on what's floatin' my boat at any particular time. I
was tempted to post my RDD, though, as it's an amazing knife in so many ways and one that I never thought I'd be able to add to my accumulation.
