The Work Sharp Tool Sharpener: Is Super Sharp What I’m After?
Here’s the trouble. I cannot lock my elbows. I think it’s a genetic situation. I blame my parents (of course I do). Every time I attempt to pass a tool over a water or diamond-impregnated stone I get such a rounding effect that I’m sure were I to continue, the result would be a new type of tool that could remove wood from around a corner.
Please, all you hand-tool gurus don’t write to me with directions on how to stand, where to place my arms or how many times to pat my head as I rub my stomach. It won’t help.
I want my chisels sharp like my Dad’s. There were times when Dad was sharpening his tools, that he’d have perfect 1/4″, 1/2″ and 3/4″ patches of skin on his arms that had no hair on them at all. I don’t know if he was testing his sharpening abilities , please don’t try this at home , or just showing the young guy a thing or two about woodworking.
As a result, I turned to machines. If I can lock the chisel in place or at least hold it square as I move it into the wheel, I can obtain a fairly sharp edge , something that would cut when and where I needed it to. These machines produce easy-to-achieve, consistent results.
The water-cooled hollow-grinding appliance became my best friend. Finally, I was able to get my chisels as sharp as Dad’s. But, I wasn’t fond of the messy water and I know that some sharpening experts feel a flat bevel is stronger and holds an edge longer than those that are hollow ground. But with this machine, I could get great results and go back and touch up the edge whenever I felt it was needed.
These past few weeks, Popular Woodworking has had a Work Sharp Tool Sharpener ($200 at many retailers) in the shop for review. Work Sharp is a dry-sharpening system that uses tempered glass wheels and abrasives to put an edge on chisels and other flat tools. And, it has an attachment for sharpening rounded edges, too. It’s a product by Professional Tool Manufacturing (PTM) , the company that delivered the Drill Doctor.
It was time for me to clean up and sharpen my chisels (pictured here with one already through the process). I turned to the Work Sharp and was happy with the results.
I followed the methods that the guys from PTM showed us during a demonstration. I started by reshaping my tools. I used a P120-grit, 6″ adhesive-backed disc applied to the glass wheel. In a short time, I had perfectly square ends on the chisels and the bevel was a consistent angle (provided by setting the sharpening port).
Next, I worked through the P400-grit disc and the P1000-grit disc and finally I reached the Micro-Mesh disc that is graded at 3600. After using the abrasive on the bevel, I flattened and honed the back of the chisel on top of the wheel.
This picture shows the end result of my efforts. I can tell you that the cut of each chisel is very good and I’m well pleased. I do notice a few fine lines remaining after the last phase. I’m planning on pushing sharp to the next level using a 6000 Micro-Mesh. I’ll let you know how it goes. I might even try shaving my arm hair. How about that Dad?

Here’s a tip: I find it most helpful when sharpening to use a black Sharpie (what else would you use when sharpening?) and color the bevel on the chisel. When you begin the next sharpening phase, you’ll notice the black being removed. This tells you when you’ve worked over the entire surface.
