I know this is late in coming, but it's been a busy couple of weeks in the shop. This is an update to my post about the client that sent me a 305lb blunt excavator breaker bar for a chisel point.

My client runs an equipment rental place about 300 miles from me and sends me a lot of stuff like jackhammer bits and great big wood chipper blades. In a very rushed call one day when we were both busy, he gave me the model name of the machine this goes to, asked if I could put a chisel point on it, and like an idiot I agreed before looking up exactly what it was I was accepting. After all, I'd never had a problem with anything he'd sent me before. What could go wrong?

A week later a truck pulls up to my shop, unloads a forklift, and drops off this 305lb chunk of solid steel. I had no idea my client even rented out full-sized excavators. Now I know.

The first thing I did was to give the client a call and discuss that this bar is likely case hardened, and that to cut it down would expose the softer steel core, potentially allowing it to deform when used. Surprisingly, he was fine with that and asked that I go ahead. Well damn.

When I posted here about this originally, I got a lot of ideas like transporting it to a machine shop and somehow hoisting it up to run it on a mill if I could find one big enough. Sorry, but that's just not practical and not happening. No, it was going to have to be old-school.

So the second thing I did was to stare at it for two full days while I worked on other orders, trying to make up my mind how to proceed.

The third thing I did was to contact my guy at Empire Abrasives and lay out my problem. He made some recommendations, and a few days later I took delivery of two boxes of 36 grit zirconia flap disks for my 7 inch, 15 amp angle grinder.

Shout out to Empire: They know their stuff. If you ever need to remove a lot of steel as quickly as possible, zirconia flap disks are absolutely the way to go. Like a knife through case hardened butter they were.

Even so, it was probably 2 1/2 solid hours of grinding before I got it how I wanted it. 2 1/2 hours for which the client paid handsomely, I might add.

And how did I want it? See the attached before, during, and after photos. The client took delivery last week and is thrilled. He still has no idea how much stress he caused me.

Done in the Hapstone RS with Premium cbn stones and PDTools cbn as my finishing stones (4000 and 10000 grit)

Can anyone help me identify this stone? No markings on the box, or stone. Belonged to my great grand father here in texas

Just got a new Sharpal 202H. Everything seemed to be going great until after I formed a bur and flipped the blade. The angle that was perfect on the first side is now WAY off on the second side. Is this thing junk or am I just an idiot? The angle finder is confirming what im seeing.

At least for me. I have been sharpening my kitchen knives with a shapton kuromaku 1000. I have been able to get them quite sharp, but always lacked that final finish. My edges were always somewhat «rough» to the touch. I recently applied some inexpensive stropping compound (Tormek PA-70) to my leather strop, and boy did that make a big difference for me! Nothing changed in my method, the compound was the only variable. After a few rounds of stropping, I now have shaving edges!

I used a chinese diamond plate to fix the tip and then shapton glass 220, shapton rockstar 500, shapton pro 2000 and king 6000 for the bevel. The polish isn't perfect yet, but at least it cuts now.

I have sharpen Western Knives before, but this will be my first time sharpening Japanese Carbon Steel knives. I have not really sharpen the tip of knives before, and was wondering how I can sharpen the tip of this Yosikane Gyuto?

This will also be my first sharpening since the knife was first purchased (As you can tell by some minor imperfections on the edge.)

Thank you!

I currently have a SHARPAL fixed angle system, it works good but I am curious how the work sharp Ken onion 1x30 style system is? Honestly like the rest of us I’m a sharpening enthusiast but not a professional, like my mirror finishes and sharp knives but not so much that I want to dedicate stone time to it.

What’s everyone favorite way to sharpen knives to a hair whittling mirror finish that doesn’t take an hour?

Looking to add 1-2 of these smaller stones to a knife roll mainly for touchups but potentially a bit of actual sharpening. Not the biggest fan of rods for chef knives nor relying solely on a strop for it.

I have a 1x6 in 3k ruby so that's probably the go-to for normal touchups. Thinking something that's versatile and lower grit to compliment it, maybe a 1k dmd diamond resin 1x6 or another brand. I am basically avoiding the temptation to throw in a very low grit stone as I can just bring a full sized if I'm doing significant sharpening for others as a favor.

Mix of cheap stainless (kiwi) up to blue and white steels and probably some random higher end stainless from time to time, nothing extreme as far as materials

Hi all,

I'm regrinding some chisels on my tormek T8 with the sg-250 stone on it. I had an out of square chisel of 32mm which I wanted to true up and sharpen, but it felt like forever to get to the last tiny bit (top left in the image). Regraded my stone many many times in between.

Question is: how do you speed up your regrinding of these wider chisels? Is the sg-250 stone even the right choice for this work?

Thanks!

Hello, my Kershaw dimension that I have EDC’d for 10 years and has been sharpened many times and over time I have made 2 bevels.

Overall the knife is very sharp but is there a way to fix this without taking off to much steel?

I realize I had sharpened at way too low of an angle and that’s what has caused the 2 bevels.

I now have a work-sharp fixed angel sharpening system that I hope to use to correct my issue.

Any help or input is appreciated!
