I recommend giving it a shot whenever a fixed blade manages to catch your interest. I thought about what kind of folder I generally prefer and the manner in which I carry and use them, and tried to find a knife that emulated that as closely as possible. Rigging that Cold Steel neck knife with a Tek-Lok via paracord turned it into an EDC masterpiece that I love so much that I've commissioned a tool steel version of the knife (as easy as AUS8 is to maintain, I use it so much that I have to break out my sharpening equipment every three days if I don't want to hack and saw at stuff)
A pocket fixed blade might just be the ticket for you, depending on your style of carry and dress. You might consider picking up a CRKT SPEW or Minimalist and seeing how you like it. There's a very different feel and capability to fixed blades that I didn't appreciate until I started regularly carrying one. Once my commissioned knives are completed, I'll have more fixed blades in my rotation than folders. That's how drastic and how much better the experience is (for me)!
There are a number of fixed knives, both commercially available and from makers, that are designed to be carried in the pocket with a low-visibility sheath setup. I don't bother with that, living in Tulsa where people can be seen walking around with Taurus Judges strapped to their hip, but I do rest assured that I could go fully concealed without issue or inconvenience.
There's a strange kind of satisfaction to using a slip joint. Many people here enjoy their slipjoints partly because they associate them with family members they recall carrying and using them, but I have no such lockless lineage to emulate. I think there is something fundamentally enjoyable and inherently (dare I say it) classy about them. Especially ones with half-stops. Click, clack, cut, clack, click.
Agreed on all counts, minus the woods venue. It's funny - I greatly dislike most (not all) locking folders with blades shorter than 3.5", but I love my Böker Peanut and my largest slipjoint has a blade that sits well under the 3" mark.
Short handles are a plague in the fixed blade world! If one can't get a comfy and confidence-inspiring grip, one won't use the tool.
And, hey, you don't see me listing my 0452CF for sale. I carry and enjoy carrying the thing even if I almost never use it. Besides, I totally impressed the crap out of the gun store knife guy when I broke that out after he tried to impress the crap out of me with his 0770CF. We both had a special knife guy moment of mutual appreciation of taste. Priceless.
