Lasers were my favorite type of knife but I have been gravitating away from them. I have or have had pretty much all of them in the various makers, versions, vintages, sizes and steels, so have had a good look around at them. I do like lasers' cutting performance, I highly value a knife that glides effortlessly through food. But, I have also discovered that I like a knife with a thicker spine near the bolster for comfort and for most of the spine for rigidity and the additional weight it provides. I also highly value a knife with a thin tip so like knives with a strong distal taper and thin tip. My favorites are Gengetsu, Wakui, and Ryusen Blazen.
Amongst the lasers my favorites all around are the Suisin inox honjaki and the Konosuke hd2 older version with the flatter profile and long skinny handle.
Favorite grind: SIH
Favorite profile and blade shape:
older HD2
Favorite handle: SIH and older HD2
Favorite kanji: Ginga
Favorite blade thickness: HD2
Favorite steel: to be determined
Things I dont like: exposed machi, english printing on blade, extra thin blades, too much belly, rust, too light of a knife, blade heavy balance, and big handles.
Another thing that I like about Sanjo knives as compared to Sakai knives is that the Sanjo knives are a bit longer and combined with their extra weight I prefer their 210 knives over the Sakai knives which just seem too small, the Sanjo 210's are a better fit for me.
I'm still in the laser game, have a used Tadatsuna inox 240 gyuto on its way
