Hi folks,

I was a hand plane jointer until recently when i grabbed an old walker-turner model from the 40’s. I see some very affordable knives that are 3/32 thick instead of the original 1/8. I wonder if this is safe and ok to use. My initial thought is that they are pinned down to a flat housing with set screws, so it shouldn’t matter. But this is aquestion that doesn’t come up at all in google searches, so i thought I’d better be safe than sorry. Thanks for any experience you can share!

You should be just as safe as everybody else using them. I’ve seen 3/32 ones for about $15 and nicer Freud ones at 1/8” inch for $27. For something that I’m gonna get resharpened, I’d pay the extra $12. Of course I’m talking 6” knives.

Yes, these are 6”—well, 6 1/16 according to spec.
