Picked up this blade couple months ago from James in Australia. Some impressions. Paid around 150.00 shipped from down under. That is a good price for the Tojiro powder.
When I first held it seemed on the heavy side at 8.83oz. I sharpened it raised a burr easy on Gesshin 4K. As began using it this knife started to grow on me. It has a really fine convex grind with the extra weight just falls through food. Edge retention is excellent.
The Akifusa was sharper OOTB. Tojiro JMO has better grind and is thinner behind the edge. I am not expert enough to tell difference between SRS-15 & Tojiro powder, both are excellent stainless.
Have been a long time fan of Tojiro Stainless cleavers they have great grinds. Not so much with the cheap carbon blades that can come thick as a brick. Always thought the DP was OK good intro to Japan blades.
If you don't mind a little weight this is a much better blade than DP. Does not need any modifications is a very good cutter with perfect balance joy to cut with.
