I have a machined aluminum fire piston that I'd like to trade for a new or slightly used Fenix L2D CE (LED flashlight). I'd also trade for a Fenix P2D or P3D. I have 2 of these left, I'd trade both of them for some blue class Benchmades, some Spydercos, and other knives, just email me with options.

>Machined 6061-T6 aircraft grade aluminum (Will never rot, and much stronger than wood).
>3/4" diameter wire brushed grip cylinder with 1/2" bore piston.
>Piston has a tinder retainer machined into its face.
>O-Ring seal provides 100% airtight seal to ignite tinder faster. Also keeps water out while stored.
>Tough materials and construction allows this fire piston to be ignited by striking against hard surfaces, instead of hurting your hands like many fire pistons require.
>Tinder can be stored in the large cylinder while the fire piston is not in use, the water tight seal will keep it dry.
>I machine these fire pistons myself in my machine shop in Grand Rapids, Michigan USA. Tolerances are held very tight for excellent compression and reliability. Each piston is lapped individually to it's mating cylinder for a precision fit. I test each fire piston and usually get ignition on the very first try.
>These fire pistons are of my own design, and are the result of many prototype models. I found that the method I use is more reliable than a two hand fire piston, and causes much less fatigue on the hands during practice and actual use.
