Tsunehisa SRS13 Polished / Western Handle 135mm Petty
Tsunehisa Hamono is a brand located out of Tosa, Japan. Their aim is to bridge the gap between bringing consumers quality handmade knives, at an affordable price. Because not everyone wants unnecessary bells and whistles driving the price up of their knife when all they want is solid build and good performance.
SRS13, you're probably thinking that sounds like a chemical formula. You're partially right! SRS13 is part of a series of offerings from what we call high speed powdered steel (HSPS). Basically a concoction of ingredients brought together in perfect metallurgy harmony to produce one of the most corrosion resistance knives out there. To get all sciency and geeky, the grain structure is ultra fine and the carbide composition keeps this steel extremely sharp for a very long time, outlasting other HSPS like SG2/R2.
A Suehiro CERAX 1K whetstone will cut this steel easily, keeping sharpening manageable as you maintain the edge by regularly stropping with diamond compound. That is our recommendation to ensure your edge stays sharp for up to 3 months of heavy use on the line, roughly equivalent to 1+ years for you home cooks.
If you find yourself appreciating smaller knives, for smaller all around tasks, you may be looking for a 135mm petty. At this length, it can still be used in hand to comfortably pare an apple, or on the cutting board to finely slice some shallots.
