Thank you gents. The size is ok, perfect for hand held, good for bench honing also. Sure, a bench stone of this quality would be a dream but currently impossible with my small budget. But rather a small high end stone than a large without a noteworthy result.
I went for a smaller affordable one too. Not only does it make a high end quality stone affordable, but I also find it forces learning technique and skill. Plus I really like hand honing. I find more control and working on old odd blades that are not perfectly straight work out much better on these size stones and hand honing.
Is that a Suita tomo?
