I understand. I grew up with non-locking slip joints. Locks have never been important to me in general as I don't depend on them. I don't do any serious "fixing" with a SAK. I would use regular tools or perhaps my Vic Spirit or SOG Power Lock. The thin blade on SAKs is an asset, not a detriment. (corrected the spelling) Added: I find SAKs occasionally with broken blades. I have never broken a SAK blade in the 30 years I have been using them. I guess folks did some serious prying with their SAK to do this. The thick blades found on many modern knives are simply un-necessary and reduce the cutting efficiency beyond a quick slice.
