I'd like to point out that the more tacks you have the less sharp they will be in total. The surface area will be spread out over them and they will not penetrate surfaces as easily.NS wrote:I shall make it known that if you don't pick me to judge, then you are a damn fool, as I have a mind sharper then 3000 tacks.
The Bed-Of-Nails trick works on this same principle.
