so, i put some of the new KaBar micarta on the relatively new BK2 (second gen, second gen sheath, not the latest sheath), and they fit as you'd expect, pretty darn well. edge to edge they're quite flush and good.
there's an odd ridgeline on the top the micarta though, that is not present on the grivory handles (which are a new style from the Camillus if nobody has notice before ;>) i don't recall this ridgeline on earlier KaBar micarta, in particular the ones on the BK77 and from when i saw them at Blade 2009, and will have to compare soon. in many ways, i used to really like how smooth and finished the Camillus micarta was. they felt... machined somehow, perfect. the KaBar versions are of course machined (CNC ya know), but have a completely different feel, more like the factory handles, but MORE solid feeling...
i'll leave them on for a while, and see where that leads me. they feel substantial and good. they probably affect the forward balance a touch, but that's okay, the BK2 is not a mainline chopper for me.
now, in a fit of amusement, i got out my EDC Machax, #20 written on the inside handle (solid tang, thank you very much). this one features SOLID EstaLoc material handles, a lot like cutting board material, very dense, very heavy... put on the micarta - hole for hole perfection, what else did you expect?
alas, though, the belly of the tang, has a TOUCH more beer in it than current Beckers, and it's not flush. there's a little tang extension on the bottom side too that sticks out - will take pictures, but it's one of those things that's really hard to see. feels pretty good though, and we'll see how that plays out with use, with or without gloves. mmm.
so, if any of you all have older Beckers, Patrol machetes, all that, try out the micarta.
i'm also pondering what it might be like to fill the factory handles with resin, to completely make them solid, sanded flush and possibly get some slightly resilient liners, and put the whole shebang together. should make an interesting experiment.
