Benchmade, Microtech and Piranha all have good warrantys. Benchmade and Microtech will make you jump through hoops that will cost you 3 to 4 shipping charges making you send it to a dealer, the dealer to them, them back to the dealer and the dealer back to you. That's rediculous and unessesarry.
These knives are not difficult to replace springs in if you have the right spring. There are a few little tricks but if you need help you can email me at
nick@nicnac.net and I can walk you through it.
I hear that JD from roadside imports has a very good selection of springs so you can get all you need from him with one shipping charge. My advice would be get 2 or 3 for each so you have them.
One caution. Those little tiny springs under the buttons are boogers sometimes. They'll take a mind to fly off into the air somewhere and can land in the darndest places. When you take your knives apart get yourself a big plastic bag and disassemble them inside the bag. That way the little booger has less chance of getting away.
Heres another. When trying to fit the spring ear in the blade hole AND getting other ear down into the frame and over the pivot it's much easier to remove the stop pin. That way you can fit the spring in both places and get it over the pivot with no tension on the spring. Once both ears are fitted and the pivot pin is through the blade press the blade flat to the bottom side of the chassis and torque it up to just a hair past the open position then stick the pin back in.
Does any of that make sense or am I rambling??
If you don't want to attempt it I have a friend that could use a few extra dollars and he won't charge you what shipping the three back would. Email me and I'll send you a couple of folks that can fix em up for you.
Shame to waste such nice knives.
OH. The Microtech TRI Wing (toxic waste) screw driver bit can be jerry rigged by using three stout paperclips. Take a piece of a coathanger (wire guage depends on the span you need) and take 3 paper clips. Place the paperclips around the hanger. You can actually use the screw holes to help align the tips. Only leave a short nub sticking out because the metal on the clips isn't hardened. Take some thin wire and wrap it around as tight as you can get it. You might even want to paint a little epoxy or JB weld around them. When it sets up cut the hanger / paper clip combo to a usable length and remove the screws gently. Use a good amount of downward preasure so the clips don't slip out or bend.
I am rambling,..ain't I??
Well. hope it helps. If not we'll get you fixed up one way or another. Heck, if you get the springs you can send them to me and I'll fix them and you pay return shipping.
RECOMMENDATION: Buy PROTECH knives. Dave is the absolute BEST. If you call and need a spring, Dave will send you TWO. All NEW PARAGON knives will be handled the same way since we think Dave is so cool!
