My many LM multitools have served me well for decades, and I never leave the house without one or more on my person. Most of mine have been acquired second hand, and, while the Leatherman warranty department has taken very good care of me over the years, keep in mind that they clearly state that only the original owner is entitled to warranty coverage.
Remember, I'm a dyed-in-the-wool Leatherman fan, a true believer. But if I had a $50 budget, I would not limit myself to Leatherman. The Skinth holster in which I carry my Surge cost more than $50. The Multiforce has a 5 year warranty, as I understand, which means you could put a lot of EDC miles on it before you'd be out of warranty.
If I could only own one multitool, it would be a LM Wave. But if I wanted the functionality and the fit and finish of a Wave for $50 or less, I would include a Multiforce on my short list. Sorry for jabbering on so much. Well, no, I guess I'm not really that sorry. T-A
