It seems the laser operator was asleep at the wheel this week, first he wasted 2 sheets of 1/2" plate ($$) and then made something like these..... Actually they were exactly like these with 1 minor exception! And do I need to remind you that we are the overkill guys! The exception is that he cut from 3/8" rather than 1/4"!!! Now we like strong but these are Silly Strong However, there is no effect on their performance, but enough beef that we will offer about a jillion year guarantee on them! We are going to sell them off at a very fair price of $25 a pair, our normal price is $28 on them so they are not free but the normal ones are only 1/4" thick. So, if you want Silly Strong pick up a few pair! They were made in the 2 1/2" and 2 3/4" widths and we have 100 pair of each.....And don't forget the CK510 Discount either, that makes them $22.50 a pair!!
