I’ll add my amen there too. I’m not a fan of super highly polished edges on a pocket knife. Those belong on my straight razor.Mumbleypeg wrote: ↑Sun Oct 27, 2019 2:00 am Cutting a tomato is a lot like slicing bread. A "toothy" edge works better than a shaving edge. Same for cutting steak.

Filet a paper towel or cut phone book paper...
But I've been hand sharpening so long now that I just check for a wire edge and strop.
I will thumb the edge a bit and that tells me everything I need to know.
THis is what I do as well. I've learned to look very closely at the edge (practically studying it) - I can now see tiny flat spots or other issues with inconsistently sharpened bevels - to me, getting both bevels perfect all the way down to the edge with the Lansky rig under close inspection, then a feel for (lack of) a burr ... always comes up with "close enough" to me, as I know it will cut if it passes that testBatJak wrote: ↑Mon Oct 28, 2019 2:32 pm In my youth I thought I had to test the edge every time.

This made me laugh! It is also my method. I test on paper at home then take it to work. The shrink wrap will find any imperfections in a hurry.Railsplitter wrote: ↑Sat Oct 26, 2019 4:35 pm At home I usually use phone book paper for the initial test but my favorite way to test sharpness is to cut some shrink wrap while it's tightly wrapped around a pallet. We have hundreds of shrink wrapped pallets at my workplace on any given day.
Once I get the blade sharpened to my satisfaction I'll take the knife to work with me and do a final test on some shrink wrap. The shrink wrap is delicate and it responds well to any imperfections that I might have missed along the edge. Fortunately, I rarely need to do any follow up honing but I use the final shrink wrap test to confirm that.
You're not the only one on band-aids sir. Right now I have one on my right thumb with a slice on the outside edge, the blade was sharp. On my left thumb is one not from a blade, but from a belt sander when I was shaping a knife handle.Working Edge wrote: ↑Tue Mar 30, 2021 3:39 am I use my thumb for edge testing, followed by shaving of arm hair.
Sometimes I use the number of stitches as an indication of sharpness after inadvertently hooking my thumb over the edge while wiping down a freshly sharpened edge.
Just kidding about the stitches, but I do indeed use a lot of band-aids....!

When I sharpen kitchen knives I use a paper towel to clean the sharpening stone residue off the edge. The slightest bit of inattention and my thumb or finger needs band-aids. That is not my preferred method of checking sharpness, but it does work! I do not normally try to check the edge after sharpening. The first tomato or plum will be a test.Working Edge wrote: ↑Tue Mar 30, 2021 3:39 am I use my thumb for edge testing, followed by shaving of arm hair.

I find it comically ironic that Case offers a band-aid dispenser/holder....!dlr110 wrote: ↑Tue Mar 30, 2021 3:46 amYou're not the only one on band-aids sir.

I think we might be surprised at what all CASE and maybe some other companies have their logo's on.Working Edge wrote: ↑Tue Mar 30, 2021 4:12 pmI find it comically ironic that Case offers a band-aid dispenser/holder....!dlr110 wrote: ↑Tue Mar 30, 2021 3:46 amYou're not the only one on band-aids sir.

Roll up ur pants and start shaving ur leg...hair come off...Sharp!!!!StrawHat wrote: ↑Sat Oct 26, 2019 10:57 am I see in this section many threads about various ways to achieve a sharp edge. What I do not see is how you are testing that edge to determine if it is sharp.
So, boys and girls, what is your favorite method for testing the edge of a newly sharped blade?
Thank you.
