The overall craftsmanship is refined, with concave hollows worked along both flanks using a sen . However, as mukoumachi-nomi (mortise chisels), these two seemingly superior Tokyo chisels are actually less practical than the lesser-known ones currently listed on the site.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThey have a fatal flaw, which is especially noticeable on the 3mm chisel. If you look closely at the third and fourth photos—setting aside the lamination lines on the bevel and viewing it strictly as a cross-section of the blade—you will notice that the cross-section is not a true rectangle. The line representing the ura slopes upward to the right. In other words, the reference registration plane of both chisels is tilted; if used to chop deep mortises, the resulting mortise will veer off at an angle.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThe tilt on the 3mm chisel is too severe to correct through subsequent sharpening, meaning it is best repurposed for paring tasks, such as cutting grooves when making plane bodies (kanna-dai). The 5mm chisel, on the other hand, can still be trued up by re-flattening the ura.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003c!----\u003e\u003c!----\u003e","brand":"TENMOKU","offers":[{"title":"3mm","offer_id":49920642121966,"sku":null,"price":11000.0,"currency_code":"JPY","in_stock":false},{"title":"4.5mm","offer_id":49920642154734,"sku":null,"price":12000.0,"currency_code":"JPY","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0162\/5326\/files\/DSF1328_459af61d-d6dc-4df7-867f-0b601325947f.jpg?v=1793496946","url":"https:\/\/tenmoku0701.myshopify.com\/ja\/products\/mukomachi-nomi-japanese-hand-made-mortise-chisel-by-mitsuki-3mm-5mm","provider":"TENMOKU","version":"1.0","type":"link"}
