Judging from my Dog Father, the large handle was made for .250" thick blades, it's a bit too small for .285" but Dan made it fit any way.

The Basics were all .250" so he was able to do the same thing with the DM.

The Small Swamp Rat Handle was made for .1875" thick blades. I don't think he can shove in another .100" of steel.

I think a ~DM around .200" thick would be nice, but not the same thing.
