those are all jason's guns. ripper 2, ccm pump, another pump, d2, and the quest.
so here's some of the answers to your questions:
yes, that's a scythe in the picture. but it's a lot (well, maybe 1/2 inch) longer than a scythe 2. it does come from a scythe 2 blank and it take a little modifying, but they work like a charm. in fact, the "quest scythe" is better, in my opinion, than a scythe 2. and i have a scythe in my alias and one of only 2 in my gz. the quest scythe is longer because the blanks are longer; jason has to cut the bottom 1/2 inch off to fit in a timmy trigger guard. fortunatly, you don't have that problem with the quest. you can accually 3 finger the quest scythe.
yep, it's fast.
i don't know if the other designs (razor, katana, etc) are going to be options, but i believe they will be.
and yes, jason should be making them soon enough, but he feels an obligation to the customers he currently has, first. jason't nothing but class and his work, make that, his ART speaks for it's self. i assure you, how ever long you have to wait, it's worth it in spades.
