That's cool bro. Congrats. Much more that $300 is pushing it, but that's just the high end. It's not outrageous by any stretch. I was just saying you could do about $15 better around here. But now you got one without the waiting, so there's that. You're going to absolutely love that thing. It's one of my favorites (don't tell my Howling Rat I said that though).
The longer 7" Spec Ops sheaths fit those great. They're like $30-$35 all around the web. I use those for all my knives, but that's just me. They are mid range in price, and they have niether of the issues that you get with kydex and leather. Kydex marks your blades, is noisy, and has to mid-ride on your belt, and leather is weather sensitive. Just my 2cents.
Now go get your Mini Mojo before it's too late.
