SHBM work in progress

J. Oeser · Aug 12, 2011

I have had some good results from a satin finish Scotch Brite wheel on my 8" grinder. I was able to blend a nice zero edge convex on my B11 and it all turned out great. I have since used some super fine Scotch Brite belts on my B11 using my 1x42 grinder and I actually like the results better. With the wheel you have to make two or three passes on the blade and the finish is more difficult to get even. With the belts it comes out very nice.

Here is a Rat Warden I recently stripped and put a satin finish on just for practice.

I had the luxury of using my belt grinder to grind out the dimples on the handle then I used stripper on the blade which left behind the gray dull finish. The only way I could get that off was to use the grinder and sand it down ever so carefully. I could have used the Scotch Brite belt exclusively but it would have taken a long time. Also, the belt allowed me to blend in the zero convex a little better than the wheel. Regardless, I think you will need some power tools to get that blade clean. Either that or a lot of elbow grease with sandpaper.

I am certainly not the font of all knowledge and am new at this myself but PM if you have questions and I'd be glad to help.

Did you only try the stripper the one time? If so, do it again for longer, it may take a few times.................

Sigh. If you're willing, but don't want to go crazy, then try a combo of Randucci's suggestion plus Safetyman.

I don't know the nature of the undercoat -- but it isn't unusual to treat surfaces to improve coating adhesion.

Could the powder coating Peter noted have been somewhat irregularly impregnated in the steel?

Also, I skimmed, but did you note where one can find the tal strip?

Thank you gentlemen for all of y'alls insight. I have a decision to make and some more work to do. Sorry my progress is slow, I just don't want to jack up my Mistress and get into a situation that can't be resolved.

Thanks

I'd like to see is pics/videos of some of the "equipment/tools" used. Ie grinders, scotch brites, ect...

I know what they are, but seeing them in use whether re-profiling, stripping, or creating a satin finish would be great.

Here is a pic of my entire kitchen table getto shop putting the smack down on a hand rubbed 400 grit satin. I opted not to go the power tool route as I figured this would be more of an opportunity for her and I to bond.

I post more detailed picks of the work later but I think everyone gets the idea so far.

Looks like plenty of "bonding" time remains

Are you sanding vertical to the length of the blade or horizontal?

Yes, by the time this is done we will be well acquainted.

With the grain only. Spine to edge / edge to spine only, anything else and I would end up with a very ugly lady.

Flatsman007 · Aug 14, 2011

And now for some more wip

Notice some undercoating close to the edge in this pic. That's not the top layer of black coating but the dark gray under layer that I am sanding.

These pics are after about six hours of sanding with 400 grit on a block of wood and or my fingertips in the hard to reach areas. She is starting to take shape.

Now I have a question. In a sale thread for a different Busse I saw a comment on this and thought it might be damage. After removing all of the coating on one side as you will see close to the edge thare are small pings evenly spaced one inch or so apart the entire length of the blade until it tapers off. They are all identical semi circles that may have been circles before the edge was ground. Alyone know what they are or why they are there? They a not damage nor do they damage the blade.

Well thanks for looking. Now back to work.

That's all I could figure also.

Looking good lots of Infi dimples are'nt they beautiful. :thumbup:

Flatsman007 · Oct 2, 2011

All of the talk about the 1/300 made me want to revive my wip thread. She is not done yet, I have since hand convexed a nasty edge on her. I'm also waiting on a very special sheath from Leatherman. Dwayne sayes it is going to be special and if he sayes that I'm sure it will be. I'm gonna post pics of the final work and sheath when it arrives.

Thanks brother. It all started with your willingness to part with her. This was the first Grail I have had the joy of scoring.

taking that old smooth coating off is a pain in the arse. I have done it several times and it is so much harder to remove than the newer coatings that I can only imagine how expensive it was to put on that coating back in the day. Those are definitely Rc marks. you won't find that on most other brands of knives. Someone takes their Heat Treat very seriously.
