on tackle warehouse the tail looks brownish not reddish ? Maybe its not a good representation of the color ? Looked lite oxblood laminate over lite brown and the brown makes the tail.
Did I give you a # 197 recipe ? Is it Cinnamon with black flake ?
I was thinking butter knife too,, as CNC said . I remember the swim baits. But it would be to thin I thought. But maybe if you JB welded 2 of them together.. Hmmmmm .
I use scissors. Cut while plastic cooks and molds cool.
Also I never leave pucks.. Pour the left over into molds then it is way easier to cut up later.
