Spyderco Delica 4 sg - I've been using this one for a decade, but recently purchased a
Spyderco Delica 4 ffg - mostly to find out if the enthusiasm is justified. Jury still out, but meanwhile, I came up with a
Spyderco Native - got at a super price because the edge was chipped, but easily sharpened to perfect. Then I discovered the
Buck Vantage - that I like so well that I now own large and small Selects and a large Pro. My (almost) EDC, however, is a ten year old
Victorinox OH Trekker - probably the most useful of them all.
Every day I have one or more on me, along with a pliers based multitool. In addition, I have an assortment of SAKs, Bucks, Moras, Opinels and Leathermen accumulated over 20+ years that get occasional and seasonal use. I admire some of the pricier makes, but have no interest in acquiring any. What I have serves me well.
