Paul, that is a good suggestion about sliding a knife to one side or the other to fix the knick problem. I had seen that recommended before but had forgotten about it. I am not sure how to tell how sharp the knives are. What I do know is that the finish on planed boards is not as smooth as boards I run through my DW735. Does that indicate dull knives? I assume it does.

Also, not sure if it is best to post here or start another thread, but I have seen prices ranging from about $45 all the way up to $200 for what look to be the same thing – HSS knives. At this point I don’t want to put the money into a spiral cutterhead or carbide knives, but once I verify this machine checks out and I sell my DW735, I plan to look into one or the other a bit further. I am not sure if it would be worth the money yet as my planer gets used maybe 2-3 hours a year.

These knives on Amazon say they are for the DC-380 planer:

However if I scroll down it says they fit the 22-677 and I have a 22-675. When I searched for 22-677 on Google, I didn’t come up with much except replacement knives, so I’m wondering if 22-677 is actually the part number for the replacement knives for a 22-675 planer.

At any rate, I would appreciate any feedback anybody has about these knives and whether or not they will fit.

Also, I know I can probably find a bunch of info on this by searching (haven’t had a chance yet), but since I’m asking questions I’ll go ahead and ask…as far as sharpening planer knives, is there a rule of thumb as far how many times you can do it before they need to be replaced? I know the knives in the planer have already been sharpened once. There is a sharpening place about 15 minutes from my house, so it probably wouldn’t be too bad to get them sharpened, but from what I’ve seen online, it’s probably easier to spend the money to replace the knives vs taking a chance on having to change them twice if for some reason the sharpening job doesn’t fix the problem I am having with the planed wood not being as smooth as I would like.
