Axminster professional ultimate edge help

Hi, I’m looking to get the AXMINSTER PROFESSIONAL ULTIMATE EDGE, for a little knife sharpening business, but it only comes with 60 and 120 grid belts, and I been struggling to find higher grids, something like 3000/5000.
Do they existe? If so where can i find them???
Thanks for your help!!!

Hi,
Just put “Ultimate Edge” in the search bar on the Axminster web site, it shows at least 10 different belts.
Hope this helps.
Keith
