I took a long time to take this decision, but finally I am selling my Zakuri Kurouchi Sabaki Bocho in Blue #1 with 150mm blade. I got this knife earlier this year from Jon @ JKI. The purpose intended were tougher tasks around meet in kitchen (de-boning etc), but somehow this knife does not fit my style. This knife can definitely do tougher tasks in the kitchen. If you want to work around the bones on regular basis I would propose chaining the blades geometry a bit (to make the edge stronger). This knife would be also great for somebody learning hand sharpening - the Blue #1 feels great on stones.
The knife has been sharpened 3 times since new - last time just 2 days ago, so it will arrive nicely sharp. There are sharpening marks on the blade (and two small spots on the ferule where I accidentally touched the stone during sharpening), but I managed to keep the Kurouchi untouched. There is NO rust. The blade was oiled with camellia oil after sharpening - the handle (HO wood and water buffalo horn ferule) got bee's wax & oil treatment
150mm strong blade - there is absolutely NO flex. The blade has simple "shape" - the angles change only very slightly where the kurouchi starts. I would not describe this knife as "wide bevel".
blade is 150mm hell-to-tip
height at the heel: 37mm
width at the heel: 4.7mm
width at 1/2 the length: 3.3mm
width 1cm from the tip: 1.5mm
85€ + shipping from Germany (the knife is $140 new and then needs to be imported to EU)
The knife will come packed in its original box.
