If you haven't worked out this is one of the best blades for a ridiculously low price you need to buy one. Rubi blades last one job if you're lucky, we used to use montolit DNA which are four times the price of these. We've even used 115 for 20mm porcelain, it's an animal, but also doesn't chip and last for ages. If it's a clever lost leader by protiler so be it. Check out the rim of the blade on the right in the picture, they just keep going!
