I got a Harbor Freight tamper proof screwdriver,it started out as regular screwdriver. I was in a jam needed a Phillips screwdriver,right now, there was a Harbor Freight in eyesight. Now I soured on this place a long time ago. But remember I need a screwdriver right now and they are walking distance. I walked in looked around,WOW that's what everyone's talking about, lots of good looking stuff. Asked someone I need a Phillips screwdriver,right now. The guy points at a 4 in one hanging on a display. I bought it, out the door I go,it did what I need it to do. So yesterday,I needed a straight screwdriver on my way home. Luckily I happened to have my handy 4 in 1 that's taken out and replaced 2 Phillips screws in dynamite fashion. So I'm trying to remove some straight screws and it's getting harder and harder I keep pushing in and turning,but I keep having to push harder and harder to keep it from slipping out. Then I looked at the tip of the screwdriver,it now has a twist to it. The good is you can tighten screws with it,the bad is you can't loosen screws with it. So I'm thinking if we can just get crooks to buy these we will no longer need tamper proof fasteners. I can't believe it,another one of those,this has to work,how can you mess up making a screwdriver. Now I know. The good is they did replace it with no problem. I almost wrote last week letting you all know I went in Harbor Freight and was impressed. I'm just writing this in fun,but the screwdriver really did make itself tamper proof. Who'd of thought cheep chineese shelving would beat a cheap chineese screwdriver. I'm going back next week for a parachute.
