I’m going to start a new thread on this because I don’t want to highjack someone else’s posting. But maybe now that we’re on the subject of jointers and nicked knives I’ll throw this on the fire! Is it the job of a jointer to provide a “finish ready” piece of material or is the jointer main function to provide a piece of lumber that is flat and square?
Same with a planer, its main function is to make the lumber exactly the same thickness throughout the whole length and width of the board.
Now, you take a scraper or a sand paper, their job is to smoothen the lumber to a state whereas you can apply the final finish.
Don’t get me wrong, I hate it when I put in a new set of knives in my planer or jointer and get a nick just as much as everyone else. But, am I going to get all anal about a small little ridge in my lumber and change out the knives right away? No, I’ll grab my cabinet scraper, hand scraper, or the sand-paper and get rid of the ridge on the face of the board. And if it’s on the edge of the board, I’ll move my jointer fence so use a spot on the knives that aren’t nicked.

Hi Jim,

I tend to share your philosophy. I nicked one of my jointer knives within a week of putting the tool in service but still haven’t replaced the knives after 3 years. Offsetting them helps but I still get nicks showing up when I joint. Same is true with my planar knives as well. But overall both knife sets still do the job so I will just scrape and sand away the ridges. I am going to have to scrape and sand anyway so it really isn’t a major annoyance.

Jim,

I tend to share your philosophy here. I’ve had a nicked planer knife in my planer for about a year.

Even though I could shift the knife a little and eliminate the ridge that shows after planing (or even replace the blades with the set I have sitting in a drawer) I just keep using it as is. I almost always hand plane or scrap the surfaces on my stock anyway so, I have not bothered with it. Granted the nick is relatively minor and does not interfere with really anything – if it wrer worse I’d probably take care of it.
