Yamashin has been producing honest, hard-working kitchen knives in Tosa, Japan, for generations, and this White #1 Bunka is a perfect example of what makes their work so well regarded. Tosa is known as one of the more productive knife making regions in Japan, turning out blades that prioritize real-world performance over flash.
This bunka is hammer forged in a san mai construction, with a Shirogami #1 core, the purest grade of white paper steel, clad in soft iron that develops a beautiful patina over time. The bunka profile combines a flat cutting section with a distinctive angled tip, making it equally at home slicing, dicing, and doing detail work. At 56mm tall, this knife runs noticeably taller than most bunkas, giving it extra authority on the cutting board and making it easy to scoop cut ingredients directly from board to pan, and the walnut octagonal handle with black pakka wood ferrule rounds out a knife that punches well above its weight.
What Customers Are Saying: Customers are consistently impressed by what this knife delivers at its price point. The extra blade height is a recurring favorite, cooks love how effortlessly it scoops vegetables from the board, and one owner specifically sought out this taller profile over a standard bunka for that reason. It arrives razor sharp out of the box, the fit and finish earn high marks, and after a little time on the stones it performs like a true workhorse. One reviewer noted the edge near the choil needed a few passes on the stones to finish properly out of the box, but called it one of their favorites once that was sorted out, and a professional cook reported getting through an 80-pound bag of carrots in under 20 minutes, high praise for any knife at any price.
Care Instructions: Carbon steel care is straightforward. Wipe the blade clean during use and dry it immediately after washing. Avoid leaving water or acidic foods on the blade for any length of time. The soft iron cladding will develop a natural patina with use, which adds character and provides a measure of protection. Each knife is made by hand so measurements may vary.

This is a great rustic Bunka for the price. It's taller than a standard Bunka's height and that is the reason that I wanted this one, for scooping cut veggies with. Razer sharp out of the box! The handle is also very nice especially for this price point IMHO.

Sales and service are always excellent, But not sure if this was a prototype of a design the edge near the choil was really not finished once I had thrown it through a few stones it was fixed and ended up being a real workhorse for the line I can kill an 80 lbs bag of carrots in under 20 mins with the small issue on the edge it became one on my favorites to use
