I own a SG2 270 sujihiki. Have been using it professionally for 3 months now. Since the Sakura SG2 lasers all have a similar F&F this info might be useful for the different models.
I have given this knife an absolute run through the gauntlet. It gets extensively used for 8hrs straight slicing 3 different roasted meats on a Sunday lunch shift from 12pm-8pm (I work in London UK, where Sunday roasts are taken very seriously!) and I have a fair idea of how it operates.
Pros:
1. It’s a true laser and one of the lightest around if that’s your fancy. Extremely thin behind the edge & a high flat grind. I’ve been in the company of the Santoku also (one of my chefs picked that up) and the grind is identical. The Gyuto’s look to be the same and I believe the whole range measures at 1.9mm at the base of the spine.
2. Aesthetically, I think it’s very pretty and unlike most, I’m fond of the laser etched Kanji. It kinda pops. It’s deep also and I’m confident it will not wear. I like it’s contemporary and minimal look. It’s also a bright knife which for me is a positive.
3. It gets RAZOR sharp and very quickly, something that I value 5mins before service. I sharpen it twice a week. After the Sunday shift and before the next one. It gets 5mins on a leather strop to bring it back before the shift starts and after I give it about 8mins on a Naniwa pro 5k when the shift finishes. I use it within the week but no where near as extensively as Sunday service. After the 5k, it’s good for the week, no rods.
4. I value its edge retention. It starts to dull at around 3.30/4pm and plateau for the rest of the shift to a semi sharp capability, which still cuts well enough. By this time of day I have sliced about 60 portions of beef rump, 50 portions of pork loin (I do not put it through crackling) and 60 portions of wood grilled lamb leg which has a dark bark to get through. It tackles it all fine. The first hour of service is beautiful and my speed in plating has doubled.
5. It cuts thin and straight and it’s amazing how the protein slides off the blade effortlessly. The subtle brushed finish ticks the food release box. It’s also a pretty interesting long petty, herbs, shallots etc.. There is a bit of rocking up the top middle and front, a welcome curve that can tackle delicate tip work prep and slicing.
6. For its weight, it’s astounding how strong the profile is and the SG2 steel seems pretty durable. At a HT of 62, this suits me. It could be higher but no chips yet or marks and in the heat of service it gets thrown around a little.
7. F&F on the handle is nice and for me a good size.
Cons:
1. Ok so the spine and choil are pretty awful unfortunately on the SG2s. Sharp edges and on a pinch grip (which I use also when slicing), you can expect blisters. I had to sand down the areas quite a bit, it’s now fine and I find it comfortable. But, it’s not my most comfortable blade. (I purchased mine from cleancut.eu, be interesting to see if F&F’s have been different elsewhere).
2. The heel tip is insanely dangerous. And totally unnecessary. It is so frigging sharp and sweeps back towards the handle. It actually creates problems as it snags pretty much everywhere if you are not careful, particularly when pulling back on produce like meat. It can ruin the integrity of the protein! Seriously, watch this one out of the box. This heel profile is on all models. Like a snake, it will surprise you! (And injure you). Again, I went to the stones on this to rectify. It’s ok now, still sweeps, but it’s not sharp and doesn’t catch.
3. I found the OOTB edge to be poor. 4/5 out of 10.
That’s all I can think of now.
Hope this sheds a bit of light on its performance.
I would give it a solid 7.5 out of 10 and I won’t be replacing it anytime soon.
