"Burrfection Knife" Sakai Takayuki by Ryky AUS8 240mm Gyuto with Buffalo Horn Handle

by Sakai Takayuki


This is Ryky’s first custom-designed knife. After years of testing every knife he can get his hands on, this particular 240mm gyuto profile is one of his favorites. After spending nearly a year of designing and redesigning, this knife is the end result. With a spine thickness of only 2mm, and weighing about 6 oz (170g), this qualifies as what knife enthusiasts like to call “lasers”. An ultralight and thin knife that knife purists absolutely love, and with a profile that has been perfected by Ryky’s personal input.
On top of everything, Ryky was able to partner up with one of the most famous blade makers in all of Japan, Sakai Takayuki.

    My wife is an avid cooker but has never had a nice or professional knife. So I was researching top Japanese knives and found your channel. Then I went down the best rabbit hole ever due to all your knowledge. I decided to buy her your knife the Burrfection Launch as a way to buy something top notch and support you. She was blown away by the knife. The feel, the excellent performance, the amazing handle, and it is truly a beautiful knife! She is in love with it and is now looking for her next knife! Thank you

    My Gift Knife

    I have a great relationship with this knife. Since they have been in the Burrfection store I’ve purchased five of them; four for gifts and one for me. They make a great introduction for folks to the joys of using Japanese kitchen knives. There are a couple of things that help make this a standout gift.

    1. They are sharp right out of the box. Many times people have no idea how easy it is to use a sharp knife and this a good example of that.
    2. The blade is thin and well balanced.
    3. The AUS8 steel is easy to sharpen for new users.
    4. Most everyone can use a great knife in their kitchen. For some it’s the first really good knife they have ever had.
    5. They have a classic cutting profile.
    6. They look and feel like the quality products they are.

    There are few items that can be given that you know will be appreciated by the recipient. This is one of them. I heartily recommend them to anyone looking for an excellent kitchen knife.

    Must OWN

    I recently turned a collector of Japanese knives watching a lot of Youtube videos and websites increasing my knowledge. I went on a limb and bought this YouTuber guy's knife. I said that knife is a great looking knife. Well, I just got the knife in and great was not the word. Its a DAMN Beautiful knife one of the BEST I obtain so far. Best Handle in my collection. The handle is pristine and the blades and logos just WOW. The knife is so beautiful I am not sure it will see the kitchen. LOL. You know-how RYKY is always giggling from different knives due to there features. Well, it's like he took the best of all those knives and compile them in designing this knife. I like how Japanese writing are well pronounce and you don't have to squint to see it. The blade polish is just amazing. The blade is so nice I wish it was even larger to enjoy looking at it even more LOL. But truly this knife is worth it the Design is just amazing.

    Finally own a Japanese Knife

    I stumbled across Ryky's YouTube channel a while back and enjoyed his knowledge and enthusiasm for knives and sharpening. When I found out he had an online store I went browsing with abandon. Fathers day was coming up and I sent some links to my family of the items I wanted hoping they would all pitch in for a Fathers Day Gift for me. When it arrived, it was not the knife I picked out from the B-stock but a '1 of 200' Launch Edition 240mm first quality knife. This is a beautiful knife folks. Really well made and sharp out of the box!. The first thing I noticed was how light it was. After slinging around German steel with (what seems like now) incredibly thick tangs this knife is really light by comparison. I imagined I would own a Japanese knife at some point but I'm glad I was able to support Ryky in some way. I love watching people who can find a way to turn their passion into a way to support themselves too. It's clear you took the time to make sure that if you were going to put your name on something you wanted it to be a quality piece. Well done Ryky; well done!
