Was wondering if anyone has used boron blades before. These are a good quality product as they are razor sharp to begin with and keep their edge very well. Generally i find exceptonal wear quality upwards of 30% better wear resistance than other blades I have used prior, and importantly, the need for me to resharpen them has diminished 3 fold. Best of all the boron blades are priced extremely well. I know they are available in Australia quite readily, is this also the case in the USA. Apparently they have a hardness of 52 Rockwell without being brittle. Thats extremely hard for a blade. Anyway have had great success with them thought others may like to know.
