I have a bunch of folders, flippers, and a few slipjoints from various custom makers & production companies.
The largest slice of the group are from David Mosier.
My edc slipjoint is a Jared Oeser (name should sound familiar, he is a HOG.

) Zulu pattern. Ask Knife Hunter if it's sharp.

But lately with the Oeser slipjoint, I've been back to carrying my Diskin Volcan flipper. Lotta blade in a thinner handle, great ergos, m390...and giving some pocket time to my first from a local (to me) maker John Gray, and he calls it a Purple Perversion. Picked it up from him @ Blade'15 and I dig it. His own hand turned pivot screw doubles as a lockbar overtravel stop, cts-xhp blade is SAS. Great flip, lockup, ergos.

Zulu Shadow. The workhorse & my first from Jared.
Patriot Cattleman. He makes about one "Patriot" American flag themed model a year, I believe, and this year marks his 3rd. Honored to have won the chance to buy this, his 2nd one, which was last year's Patriot Oeser, by lottery.
