The finds

Carbon steel develops a protective patina over time and requires prompt drying after use. Against the $170 that Sukenari (per the title) typically brings by its researched range, the $120 asking reads cheap.

Single bevel carbon steel requires careful waterstone alignment on the flat ura side to maintain proper geometry. Sukenari (per the title) at $170 is in line with its market, roughly $187 typical by its researched range.

This Sukenari (per the title) is priced where its market lives, $240 against a $257 typical by its researched range.

Mono construction means the entire blade consists of a single uniform alloy layer. At $236 this Sukenari trades right around its $219 norm by its researched range.

San-mai construction wraps a hard carbon steel core within softer outer cladding to ease future sharpening. Typical money for Masamoto is closer to $250 across 14 comparable asks, which makes $375 a rich ask.

Damascus construction reveals complex pattern-welded layers through etching, requiring careful cleaning to preserve the finish. This Shigefusa Kitaeji is priced where its market lives, $2,175 against a $1,987 typical across 5 comparable asks.

Patina formation is standard for this carbon core as moisture reacts with the exposed edge. No real gap here; Masamoto Tsukiji typically fetches $140 by its researched range and this lists at $189.

Kasumi finish highlights the weld line between the hard carbon steel core and soft cladding. Typical money for Masamoto Tsukiji is closer to $132 by its researched range, which makes $195 a rich ask.

The ultra-thin profile and honyaki carbon construction of a fuguhiki demand extreme care to avoid chipping on hard ingredients. The seller wants $699 where Sukenari typically sees $296 by its researched range.

Single bevel honyaki blades demand advanced sharpening skill to maintain the flat uraoshi and hollow ura without rounding the delicate cutting geometry. Masamoto Tsukiji at $231 sits above its market, roughly $140 typical by its researched range.

What the title claims as a specific maker is contradicted by the visible signature on the steel. Masamoto at $452 sits above its market, roughly $238 typical across 20 comparable asks.

Single-bevel geometry requires distinct sharpening techniques on the flat ura concave back. At $239, this lists above the $140 its own market supports by its researched range.

The $393 asking runs ahead of the roughly $263 that Masamoto normally brings by its researched range.

Ginsan steel offers high edge retention paired with stainless corrosion resistance, making it lower maintenance than carbon alternatives. Typical money for Masamoto is closer to $225 by its researched range, which makes $417 a rich ask.

Kasumi finish reveals the weld line where soft iron cladding meets harder carbon steel at the core. Typical money for Masamoto is closer to $208 across 8 comparable asks, which makes $543 a rich ask.

Shirogami 1 carbon steel takes an exceptionally sharp, toothy edge but requires immediate drying to prevent rust. Masamoto Tsukiji at $914 sits above its market, roughly $162 typical across 5 comparable asks.

Honyaki construction creates a single-piece carbon steel blade requiring advanced sharpening proficiency. The $1,445 asking runs ahead of the roughly $164 that Masamoto Tsukiji (per the title) normally brings across 5 comparable asks.

Shirogami carbon steel takes an exceptionally keen edge easily, but single-material honyaki construction makes thinning unforgiving. $730 asks more than the $252 that Masamoto usually commands across 12 comparable asks.
