hi all

like it says in the title.......

are these useless even if i remount on a thicker flat surface (10mm acrylic/perspex)
I have a SP1000 at home and have a rockstar 4000 in my basket and i was thinking
are these worth the 16€ just to try diamond and maybe repair some beaters, practice thinning etc
Im on a budget obviously and am not in the market for atomas or DMTs etc

I have a shibata R2 gyuto and a AO petty on the way,
all my other knives are globals and an F Dick slicer and other random no namers
I was told before here to take the Globals straight to diamond plates due to the horrible carbides
My shibata does 90% of my uses but the globals are still handy for dirtier harder work,
i can get them functionally sharp with the SP and honing rods but the edge retention
is terrible but i suspect thats just the weird Cromova18 steel?

thanks
 
I mean for 16 euros, I personally think they’re worth trying and you can learn on them compared to your shapton’s

I do want to clarify about atoma’s and see if I can convince you why they’re worth their price

Most people here use Atoma’s for flattening sharpening stones. They last quite a while and they work quickly while having a broad range of grits to flatten and prepare different stones.

I don’t think a lot of people here use Atoma plates for actual sharpening but it can be done (there are a lot of better options though)
 
Apart from your first question: poor edge retention with Globals is very common. As you noticed it has all to do with large — and I'd say clustering — carbides. If you've finely abraded a burr, a new one will pop-up a bit later — in a different place. I can just suggest to let it rest overnight after using a coarse stone, especially if some pressure was involved. A full progression at once doesn't work with this essentially unstable steel.
 
I use these all the time. They are perfect for thinning and sharpening beaters. The only real issue with them is size and how thin they are. They are really annoying to use if you don’t have a proper surface to fix them to. They slide around unless you have like a raised silicone surface to hold it in place.

Edit. I see the ones you’re looking at have a silicone backing which is good
 
While not knife shappening, Paul Sellers has demonstrated that cheap thin plates are can work quite well.
I would never thin with one though due to errant diamonds causing very deep scratches.
Personally I find working with cheap flimsy plates or sandpaper to be far too anoying to justify the savings.

Edit: what is with the shortened URL? Those things are awful.

Edit2: spelling

just thought the shorter url is neater
 
I used to superglue my plates to a flat second of wood for a base. They were only about 1mm thick without.
