Kind of on topic since sharpeners have come up a few times, Thunderbird Gear is now a Canadian dealer for Hapstone (Ukraine) sharpeners and accessories and their prices are cheap with free shipping, especially when compared to Gritomatic in the US with higher prices and paid shipping. They have a 10% off code as well until the end of May.

The Hapstone RS is the smaller "takedown" unit, meant for knives 8-9" and below with a spine thickness of 6mm and less. It can be taken apart and stored in a case for easy and compact storage. Compare that to the much worse Work sharp Professional Precision Adjust which is $100+ more with bad stones that are hard to find/replace in Canada. Also similar is the KME sharpener, both of which only have a single clamp option.

The R2 is their full size unit for knives 12" and below with a spine thickness of 8mm and less. It is meant to stay assembled.
Quick R2 review. Note that it is from 2021 so the prices quoted are quite off now.

Hapstone has a variety of attachments (not yet available at TG) such as flat magnetic tables, scissor attachments etc for the R2 which are shown in the video above. They will likely start getting them in with their next order in a few months.
The "Premium" CBN and diamond stones will last most of us our lifetimes and will easily sharpen thousands of knives. They will likely require an initial lapping to expose the grit to make them perform as they should due to how they are produced. The boride stones will last from a few dozen (low grit) if you heavily profile a lot of blades to a few hundred. The "Start" CBN/diamond stones are likely around the same range depending on use.
