Found a stash of them for sale at Gander Mountain last weekend when I stopped on the way to camp. They are expensive, but I've got about 2 dozen of the heads with 6-7 of them needing new blades. Each pack comes with 3 new tips, 6 new blades, and 6 new o-rings. They are selling them for $19.99. I bought up 6 packs of them before we start to see our annual Rage low stock crisis.
I to had seen them at our local Gander a while back but had not enough cash in the wallet while i was there I was just browsing at the time :d
They're not difficult to replace. Just take your time. Here's another little tip for you. You can change out all the blades in your practice head, and you have another hunting head. Oh, this is all for the 2 blade, I've never changed them on a 3 blade.....
With your enourmously fat fingers there is no way you could replace the blades, just buy new heads and save the trouble! >>>Ka-Tow<<<
A shop near me had some and I picked them up. Unfortunately I grabbed a 3 blade pack and I have 2 blades. Now they don't have any more of either.
