Hapstone

[R McQ]

I am aware that the specs for a Hapstone RS say max blade length is 230mm but is this hard and fast or would I be able to sharpen blades up to 250mm on it.
Would rather purchase a RS than a n R2.
Any advise would be appreciated, thanks.

Hapstone RS is a Sharpener.

And have you tried asking the company?

I recall a thread asking this very thing a couple of years ago and a Hapstone rep replied that you could not. I've seen a few other discussions that indicate the RS is limited to the 9" 230mm size blades it's posted for and if you have longer blades you should go with the R2 or V8 for blades up to 300mm/12".

I don't know if 777 Edge may have a solution that will help you, but I'll tag him here just in case he does.

I've sharpened 30 cm + blades on mine and it works just fine, as long as it's a fairly rigid blade. Your only limitation is that you won't be able to flip the knife 180 degrees without lifting the sharpener / having it hang over the edge of a table.

Have a look at this post I made in a thread about the Hapstone RS:

That looks nice! What do you reckon is the longest blade it can handle?

Check that: on their Indiegogo page they claim it can handle knives up to 9".

With the original clamps rotated outward, the space between the outside of the clamps is 170mm (6.7 inches). I have a 12 inch ruler clamped in it (below in the photos). It will easily be able to sharpen a blade of that length. I would even say up to 13 inches of blade would be fine. At a reach of 6.5 inches from the center (13 inch blade), it still has about 2 inches of rod to spare inside the stone holder tube.
