I have a Delta 37-190 6” jointer. Something I ran through it has put several tiny nicks in the blades resulting in an uneven surface after jointing. Easy enough to sand out, but I know the tool can do much better. Time to replace and/or sharpen.

Several questions:

First: (I think I know the answer to this already) I have a second old set of blades and one of them has a small nick out of the corner of the blade. Even with resharpening, there would still be a small (less than 1/16” X 1/16” nick on the corner of the blade. Is this acceptable since it would never see the wood or would this minuscule difference create an unacceptable out of balance situation. Hard to believe that these are balanced to such a fine degree.

Second: How about suggestions for a good sharpening service for both my sets of blades. A place that knows what they are doing and will get all of the knives sharpened to work properly together. Is it cost effective to have this service done?

Third: Suggestions for good quality replacements. A quick Google search gave the following results.

Original Delta brand set of three knives $111 from one source, $168 from another and $300 list discounted to $180 for another. No kidding, this is what comes up.

Other brands include Powertec and Xcalibur. They range from $15 to $25 for a set of three. Another is American National Knife at $29. Has anyone had experience with any of these to know if they are decent or just junk?

I sure don’t want to spend over $100 on a set of knives, but I don’t want to go cheap and buy a pig in a poke either.

I’ve gotten HSS jointer knives from American National Knife before and they seem decent. I have no complaints.

Just replace them. Sharpening cost just as much as replacement knives. I usually buy from Holbren or Global, and they both offer 8” jointer knives for around $20 (for a set of three knives). 6” are even cheaper.

Holbren, Infinity, Grizzly, Hartville Tool, Ebay, Amazon, Rockler, Woodcraft….all should have decent blades that will fit.

If the existing knives are sharp, you can just move one or two over slightly to get rid of the ridges they are leaving behind. That will at least get you working while you look for replacement blades – which as others have stated, can be sourced from lots of different places/manufacturers.

Thanks for the advice. It is good to know that most of these after market suppliers sell decent blades. Holbren was mentioned twice, so I will probably start there.

Thanks for the reminder about sliding a knife over. I have done that on my planet in the past with good results.

I just wish I had bought a dozen sets of Delta knives way back when they were cheap. I could sell them for a better return than playing the stock market.

Have your say...
