I regularly use and abuse a Cold Steel Mini-Recon. The lock and ergonomics are very solid, but the blade steel needs regular maintenance to stay sharp.
I like it because of the strength of the lock, but it needs regular touch-ups with the steady diet of grit-encrusted plastic and sisal rope I feed it.
My Kershaw Cryo and Benchmade Mini-Grip get regular pocket time, outside work. Both have a sturdy feel, and good erognomics. IMHO, the Cryo is one of the best cost-to-value ratios on the market.
Oh. Right. The Cryo is Kershaw's offshore 8cr-whatever steel. But, Kershaw makes sure the heat-treat is done right, so it stays sharp longer than most examples of this steel.
The Mini-Grip is available in a bunch of different flavors. Choose what you like.
