   If all seems fine then don't do a bloody thing except use them.  And enjoy!

   The objective of a microbevel on a sash mortice chisel (and all mortice chisels) is to provide a durable edge along with a bevel that maximizes its ability to penetrate. For example, you can use a 20 degree primary bevel along with a 35 degree microbevel. The low primary bevel aids penetration. If yoour current primary bevel is about 30-35 degrees, then the chisel will cut but it will not do so as efficiently as one with a low primary bevel.

   I bought two Ashley Isles mortising chisels, which have a small bevel on each side, so the wood can escape as youre cutting into the mortise.  They are about $80 each, but are wonderful to use.

   Don't worry about it until the chisel tells you it needs a different angle of attack.  The folks who made it knew what they were doing.

   My mortise chisels are several different makes and probably none have exactly the same bevel.  Moreover, none of this is very important.  Using the chisels to make completed projects is.

   “When we build, let us think that we build forever. Let it not be for present delight nor for present use alone. Let it be such work as our descendants will thank us for; and let us think...that a time is to come when those (heirlooms) will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, ‘See! This our father did for us.’ “ --John Ruskin.
