I think the birchwood are overpriced but i had got a Mizu Chef 8" on sale in the past and it's really a killer knife for $150 on sale. The edge retention, the sharpness is top notche. I had masamoto tsukiji V1 gyuto but the blade profile the low profile height of the blade never got me. Sadly these Mizu SG2 paring knife are fatty blade profile compared to other line like Kaizen so didn't use much.i've been interested in trying the 9.5" gyuto from this mizu line, see how it compares in thickness, weight, and grind to the birchwood, with the same sg2 steel but so much more expensive. i realize people on this forum don't much like miyabi, but i think some of them are interesting and worthwhile. best of luck with the sale.
