i want to recommend a product.
back in 2004, i bought a leatherman multi use tool. last week i decided that the joint holding the two halves together had become just slightly looser than i was willing to tolerate, so i asked them if i could send it in under the 25 year warranty. they said yes, and today i received a new, next generation tool at absolutely no charge (less the $6 shipping i paid to send the old one in). i really recommend these guys if you want to buy a multi purpose tool (blade, screwdriver, etc.). nobody else touches their product's quality, and they totally lived up to the warranty. the tool costs about $50, but you absolutely get what you're paying for.
this is what they sent me as a replacement.
