I was just walking through my local Home Depot, and saw that they had the Gerber Mini Suspension P on sale for under $8. I think it was $7.78 or something like that, but not exactly sure.
For the price, I think it's well worth it. It's a tad heavy to be considered a 'keychain' tool, and too light to be considered 'full size' but if you want a little tool for a tacklebox or mini survival kit or something, it's a pretty good option.
They don't list the tool on their website, so I guess they're discontinuing it in stock, hence the markdown. At least, that's my guess.
