I agree with those who've offered up the Rat 1 & 2 folders... Ontario makes an amazingly good knife. But they do tend to be $5-$10 over your stated budget (but totally worth spending the few extra bucks for). That said... if you just can't go a little higher, the Ontario Utilitac II (which can be had for $23.16 right now on Amazon Prime)... might be the answer to your question. I have one and it's probably the single best built knife I've ever seen in this price range. It is a 3.5" blade... so if that's too long for you then save an extra $5-$10 and get the Rat 2 (also have... also awesome for the price). But pound for pound the Utilitac II is very hard to beat. An amazing knfie for the money. All that said... if you can go into around the $40 range, you can buy a Cold Steel Mini Recon 1 Clip Point for about $40 these days on eBay (I got mine for $37 w/ free shipping a few months ago). For some reason nowadays the clip points are less expensive than the spear point or tanto blade shapes in the Mini Recon (these seem to run more in the $50+ range). Anyway, the Mini Recon 1 is an awesome knife for the money. Indestructible Tri-Ad Lock, great ergos... very decent AUS8A steel. Give 'em a look. Love mine!!!
