Procured them today. 8 of the larger ones and 12 of the smaller ones. Bigger ones will be in two rows down the sides of the bat where the chainsaw bar isn't. the smaller ones I'll put in four rows. A row on each side of the bigger ones. The rest I'll put in rings around the bat below the chainsaw bar.
These are the spikes:
Now to paint them flat black. Stay tuned.
