This was easily the simplest pumpkin I have done. I used the backside of the pumpkin to try different techniques. I tried routing a slot and stapling accross it, having no slot, and just using a saw cut. I thought the saw cut looked most macabre.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
