I bought one of these 7 years ago, and have used it almost daily since then. The blade always sharpens to nearly razor-sharp. The locking mechanism has never needed to be adjusted and is still tight - though not as strong as some of Cold Steel's newer models. For heavy use, you may want to consider one of their models with the TriAd locking mechanism, which is much stronger (ie Recon and Ak47 series). However, I've never had a problem with this knife or encountered a task it couldn't handle. For a "middle road" utility folding knife, the whole Voyager series by Cold Steel is perfect, and the low price delivers a ton of value for your coin.
