    They work
  

*by J***R on Reviewed in the United States on December 13, 2023*

Damaged my old blads, put these in and wow! perfect and smooth.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very sharp and easy to install!
  

*by M***I on Reviewed in the United States on April 22, 2021*

Great blades and fit perfectly in my Delta Jointer. They are really sharp and I can't believe how easy the wood glides over them. They leave a smooth face and edge everytime. Mine are held in with pressure plates, so I had to make sure they were even with the outfeed table. The blades are very straight and strong.

    148030 6-Inch HSS Jointer Knives for Delta 37-190  took 3 packages to get one that was flat
  

*by M***H on Reviewed in the United States on March 3, 2021*

I  purchased the 148030 HSS knives for my delta 37-190. Then  I saw the 148031 was a lower price and bought them as well for a back up.I took out the old delta blades and was about to install the 148030 when I noticed the concavity of the new blades. So I have returned them. I received also the 148031 and check the flatness of these blades and the two sets I purchased were both concave. I ordered a new set of 148030 and they were flat on the jointer bed and have installed them and they work well.I do not know what the differences are between the 148030 and 148031?  I measured  both with a micrometer and they are equivalent. I can not tell if the blades are different hardness. This seems to be an issue that  others have found.  Overall though, I have used the blades on hard and softwoods for over 100 bd ft and they work well. So 4 stars once I got the set that was flat
