Comments about WoodRiver 8 Piece Bench Chisel Set
These chisels look beautiful with their Bubinga handles. If you buy this set, be prepared to spend a little bit of time flattening the back of each chisel. These chisels are intended for paring and very light chopping. I sharpen mine at a 25 degree angle on water stones. The edge does not last very long and you have to polish the secondary bevel quite often (the steel is not of the highest quality, apparently...)
If you want to do more serious chopping, buy another set and grind the bevel at a 35 degree angle, or buy mortising chisels (usually quite a bit more expensive...) All in all, this is a decent set for a beginner to intermediate woodworker, and it will allow you to do good work, even though you will have to sharpen more often (that's a good way to learn!) Once you are more experienced, buy a better (and more expensive) set and keep this one as your knock around set.
So based on that, you might expect the same conditions.
The R or Rockwell, rating, which is used to measure the hardness of various metals is the key:
The R rating was not listed for those chisels, that I could determine, but it's obviously on the "soft" side, possibly somewhere near the 55 value unfortunately.
- Very hard steel (e.g. a higher quality knife blade): HRC 55–66 ( Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, and D2, as well as many of the newer powder metallurgy Stainless Steels such as S30V, 154CM, CPM-M4, ZDP-189 , etc. )
You might consider returning them for a higher quality set if they are still in new condition or a very recent purchase.
Some of the highest quality chisels are made with laminated steel like these from Japan Woodworker, but they are pricey.
There are others with good steel that won't require a government stimulus loan to purchase, but I can't not personally recommend any particular brand. Marples is one name and probably anything from Lee Valley or Sorby.
