The tool I use is not a flower, unless someone modified it before I got it. Its plated tho, so I dont think it was probably a modified tool. It is basically a very small chisel, with a sharp little end that is the size of the spot prong.
I have 2 wing dividers. I use one to set my spacing, and the other is set for the prongs.
I use Tandy spots, as well as some I bought off of Ebay in bulk. I make the slits narrower than the prongs either way, so that they stay under the spot when completed, and the hole is under the dome, mostly.
Any way you can use the old spots? I have pulled some off of old harnesses, and bridles to be reused with little problems. Sometimes its destructive to get them off tho, or a prong will break. Then I just flatten the prong out flat again, and reuse. Might take a lot of time with the tiny ones tho.
Good luck to you, JD.
