I just bought a Glestain 210mm Gyuto from Korin for ~$155 (tax included). First time being at Korin – and almost didn’t buy this great knife.
Bottomline: knife performance is great, and foods barely stick to the blade making it very easy to prep food. It is one of the few knives which has given me that revelation/epiphany feeling.
As some of you may know, the Glestain knives are known for that pronounced indentation which minimizes food sticking to the blade. Here is one video:
I don’t have a video, but I have a few photos to share.
Photo 1 and 2: Side-by-side comparison between a Glestain and a Tojiro DP gyuto. (Glestain on the bottom)
Photo 3: Center of mass/balance point is at the end of the blade (heel), before the bloster.
Photo 4: Cross view of the blade. The blade grind is asymmetric. The side with the indentation facing outward (aka front) is significantly curved. The side without indentation is much straighter
Photo 5: Push cutting results between the Glestain and the Tojiro DP. When using Tojiro DP, the onion stuck to the blade. When using the Glestain, the blade remained clean, and the diced onion bits stayed behind on the cutting board.
Photo 6: Push cutting a halved tomato with the Glestain. Vast majority of diced tomato pieces stayed together on the cutting board – instead of carried off by the knife blade, except that one piece you see stuck to the back side of the blade.
Based on my last night experience, the Glestain blade truly minimizes food sticking to the blade and therefore it was much faster to prep foods using it. Food stayed together, so it was easily to keep on dicing them finer and finer. I also didn’t have to constantly remove food on the blade.
Specific geometry comparison between the Tojiro DP and Glestain:

Tojiro DP: 195 g, Glestain: 185 g
Blade thickness at spine near heel area:
Tojiro DP: 1.8 mm, Glestain: 2.8 mm
Blade thickness at the middle area between the spine and the blade:
Tojiro DP: 1.4 mm, Glestain: 1.8 mm
Blade thickness 2 mm from the edge:
Tojiro DP: 0.9 mm, Glestain: 1.0 mm
