I have Tuskers in 155 and 125. The original ones I got had not edge started at all. the 125's just got here and they have a started edge-double bevel. I was thinking about trying to build a single edge out of the 125's. Then just when it was wharp enough, glue a schick injector blade along the edge. When it came time to "resharpen" I'd put the head in the freezer to separate the metals , clean it up and glue another schick on. We used to do that Schick thing in the 70's and it worked pretty well on the goats on Catalina.
The Tusker is a solid head. i dress up the forward edge of the piece that holds the shaft with a file. they take a good edge with a regular file. it is very popular in Aus, and many of the large Asian water buffs are taken every year with them.
Mike, if we get over to your shoot this year, i'll bring some-Semper Fi
