I don't know anything about hard surfacing in this application an that may be wrong thing to do but I would rather have an edge that's.
1/8" think in lieu of a razor edge that would hold up to 1500 acres where the knife at a razor edge only last 300 or so acres before it's a 1/4" thick blunt edge.
That is certainly a high wear area.

Not sure hard surfacing is the same as this carbide treatment Kondex uses?

I think the staggered pattern is to create more sharp edges as wear occurs. SWAG.

I’ll be running Kondex this year.
Friend put 8 in the middle of his Claas Pro-chop last season, almost no visible wear compared with normal knives.

I agree the new Gleaner knives are much better than previous. The will actually chip from a right stone hit. Might not able to have much harder. Be interesting how the kondex will live. Thanks for info.

That appears to be the highest wear area in combine chopperdom, it will be the quickest to get results from!
