About Yoshihiro Yauji 弥氏 良寛

It is not rare that a person’s childhood experiences had an influence on one’s career choice. It certainly is the case with Mr. Yoshihiro Yauji. Born in 1983, Yauji-san developed an interest in DIY as a child, and he gradually fell in love with tools made of steel. He found a very special connection with knives because knives in his own words "represent the starting point of mankind" (人間の原点). "From the Stone Age, human-beings started using knives to cut trees and eventually led to the development of civilization", said Yauji-san. In 2003, Yauji-san became an apprentice of Master Hideo Kitaoka, who is considered one of the best artisans in Japan. After more than 15 years of training, Yauji-san finally started making knives independently in 2019. It’s worth noting that he does forging, grinding, finishing, and sharpening, all by himself.

Care:

Ginsan (Gin3 or Silver #3) is a stainless carbon steel, with 14% added Chromium. Retaining the character of Japanese carbon steel, with similar hardness of Shirogami #2, Ginsan is stainless. It's edge retention is only slightly inferior to Shirogami #2, but the fact that it combines ease of sharpening, carbon steel character as well being stainless makes it a great choice for those who wish to have a Japanese carbon steel knife that is easy to maintain.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.

Happy pup. Worth it.
My dog loves this thing. It takes hardly any effort to launch the ball. Flick of the wrist kinda thing. The squeaky ball is her favorite but unfortunately you can't buy this brand of ball separately. It says compatible with any 2.5 inch ball but that's not true. We have a ton of Penn tennis balls and they are just slightly too big for this launcher. You can do it but it's a huge pain and hard to throw. Another issue is that when we first got it the handle didn't want to stay screwed together. After the first day of use and having to rescrew it together multiple times, the issue seems to have corrected itself? Either way, for the price with the comfy handle, very low effort throwing for big pay off, two balls included and the crazy excitement from my dog anytime we get near the thing. It's definitely worth it. I like it much better than the chuck it and stone random cheap brand we used to have. I'm going to try one of the balls recommended in the product pictures. I'll update if they work out.

Ergonomic and well made.
I have at least a half dozen ball launchers and this is the nicest one. As efficient as any of them and it feels the nicest in my hand. As long as you tighten the handle when you put it together, it will serve your puppy well.

Ball Launcher Poorly Made and Hard To Use, Save Your Money
This launcher was too long and thin to pick up the ball from the ground, I had to use my other hand to press down on it. The screw on handle was heavy and kept coming loose no matter how tight I made it, strain on the wrist to use. The ball holder end would often not let go of the ball when trying to launch it. I ended up putting it in the trash. I had two shorter Chuckit launchers that are much better made, will stick with them. I don't recommend this to anyone, save your money.
