I think in reference to the Police 3 model(which I currently carry a pair on duty) I think the tip goes a good way toward making the tip tougher. I have seen a few broken tips on the older police models(other models as well). In fact we have a current Deputy who has one of the older Police model with the tip broken and still using it daily. I do not think you guys are wrong for your beliefs, just understand who Sal was probably listening to when these upgrades came about.
EMT's,Military,LEO's are notoriously hard on equipment. That is why they replace, refurbish or upgrade. Durability is very important. If someone jumps out of a cruiser in the heat of the moment............oops I have to go back and grab the crowbar............not likely. Something on the person will have to make due. I totally understand, knives are not crowbars and screwdrivers etc., but unfortunately the objective of the moment supercedes the ideal tools at times.
By the way that modification to the P3 does look good. Take care all and God Bless!
