Chisel sharpening, extreme edition.

This one was really crooked on the back and no amount of sharpening was gonna fix that. So I took the angle grinder and cut a good 6mm off the tip, ground it back in rough shape and then clamped in the guide and honed on the diamond block.

Does cut pretty well now. That was the last of them, should be able to keep them in better shape from now on.

Chisel sharpening time. Well, mostly chisel restoration time, because I never had the right tools to do this properly and an assortment of ancient and/or thoroughly abused chisels.

The little honing guide I got is sadly not very good. Some chisels don't fit the inner jaws, the outer jaws for the plane blade are so poorly done it wobbles in them and the center wheel easily goes tilt.

Still, some sharp chisels were achieved, and some adequate ones.

I don't dismiss the obvious advantages of modern metallurgy, but when you are talking about #knives meant for field use, I like to remind people that a knife is only as good as it is sharp, and a knife is only as sharp as the skill of the person who sharpened it.

#Sharpening is the first knife skill. Don't even bother learning to cut with a knife before learning how to sharpen it.

In the field, toughness, corrosion resistance, and ease of sharpening using field-expedient methods are key.

Yesterday, before #cooking, I did some #Knife #Sharpening
For beginners here are the 2 best videos I found.

The tips that #EthanChlebowski gave really made a difference.
1) Using a Sharpie to make sure you get the right angle
2) Using a scale to test your pressure
3) Understanding what a burr is, how to detect it
4) Leaning the difference between stropping & sharpening
BTW, I didn't buy a $50 whetstone. I found one on the street & used that!

Not surprised that the No5 Jack plane I bought wouldn't do the job. This pic shows the blade at a 25° angle from the side. As you see, it's curved. Now it might be I don't know if this is a method used as I'm fairly new to sharpening, I presume the final edge is at 30°.

Still, I've decided I'm going to preserve my original blades for the planes and use two of the Magnusson blades I bought for the No4 & No5 planes.
I'll source one for the Jointer No7.

I bought whetstones a few years back to help keep my knives sharp. And several years later I’m still awful at it. After over an hour of sharpening 6 knives on 4 grit levels, only three of them passed the paper slicing test.
Anyone got any proven methods to do this well? Especially on larger knives?

I also remembered I left my leather strop at the workshop, so improvised with an old leather belt tied to a stool. Worked surprisingly well!

Today's sharpening tools are amazing! Using a raw file on my Sony a7rIV (ILCE-7RM4):

Image #1 is slightly processed with no sharpening. The trees atop the cliffs are not in focus.

Image #2 had Topaz Sharpen AI applied to it. Things look pretty sharp, and for most slightly out-of focus images, this would be all that's needed.

Image #3, in addition to Topaz, had Luminar Neo SuperSharp (universal, high) applied. Wow!
