I recently purchased a lot of test bars from an auction. The lot was listed as "Cat 40 & HSK Test Bars" and i recognize the four cat 40 taper bars and the 1 HSK bar in the top right of the picture but what are those two giant ones? Cat 60?
Additionally I dont have them in my hands yet so I can't easily determine brand and condition but does anybody know how much these are worth used? Will probably be for sale soon if anyone is interested.
