HB-102; a slightly smaller laminated carbon blade about 3 1/2" long and 13/16" (20 mm or .8") wide at the base. It's about .148" thick. Again, the black of the heat treatment is left on the sides of the blade for a rustic look. This is the blade used with the Saga Siglar. The base of the blade is not adapted to use with a bolster, although it could be used with the Lauri ferrule. This may be a fussier fit than using a bolster.
