I've used a pre-owned hide non gesshin blue kiritsuke tip yanagi, extra thin, sharpened up similar to the gesshin hide yanagiba I owned.
Advantage of hide sharpened single bevels is excellent wide bevel sharpening and ura work, very very shallow low spots. They have horizontal grind marks on the urasuki which I find makes for a more consistent uraoshi sharpening. Also the spine side is a bit more in line with the edge than many other single bevels, close to planar. Admittedly, the kiritsuke tip yanagi had a weird thing going on with the ura at the tip, almost like a twist, but maybe because it was used idk. Ebuchi forges stuff a bit thicker it seems, so it's just on the heavier side.
