We're pretty much all done with this line. Closeout sale. The Ultimatum is a stainless 245mm (9.65") Wa-Gyuto made from 52100 carbon steel which has excellent properties for kitchen knives and is used in several high end knives. The steel is hardened to 61 Rockwell and has excellent wear resistance. Spine thickness is 2.5mm and weight is 5.8 oz and the knife measures 46mm tall at the heel. The steel will rust if you let it drip dry so wiping it after use is recommended. The knives are sharpened with a 50/50 edge so they're perfect for righties or lefties.

The profile of this knife is very similar to the Masamoto KS. It has a nice sweet spot and an excellent convex grind that makes the knife very un-sticky when cutting through things like potatoes. When you hold this knife you will see why I think this is our best effort yet.

    5  Richmond Ultimatum - Perfection , July 6, 2016
    Posted By: Alexander Johnson

    Got this knife slightly over a month ago and it baffles me how much it was able to do. All thr other reviews were fantastic so my expectations were high. I can tell you that i was NOT let down. Working 6 days a week using this knife, i was able to keep a nice edge on it that actually lasted quite spectacularly. Whether I'm slicing maki rolls or carving through fruit or vegetables, I've definitely fallen in love with this knife. It makes me want to get another one!

    I got this knife a couple weeks ago in response to my first Richmond (Laser Honesuki) - it is ground just like my old Sabatiers except the steel is better and the knife is much lighter. I think my Sabatiers will be retired soon - these work just like them and have a much better edge retention, and I am getting used to the Japanese handles. When you get a 270 laser in stock, I will be getting it ASAP as I have found knives that have the same profile but cut even better than the knives I have used for 30 years. I am just a home cook, but grew up with Julia Child and my mom bought me a great set of Sabatier carbon steel knives when I was 15 - have other Japanese knives collected over the years (mostly Korin purchased - know the value of a good knife), but these are as good or better than a Nenox or kikuichi with my favorite profile and an ability to get a really good edge. My chef buddies are correct - these are knives with great value and great edge - I wish I would have listened to Rick some time ago - I love using a Richmond knife, and for the price nothing touches them. I have never thought I would have as agile a knife as this one - used it to do all the prep work at my cousin's funeral ceremony yesterday (I do the family event chef work) what a find. Thank you thank you,

    This is a good enthusiast's knife; I'm looking forward to getting used to it and making it my primary blade in the kitchen. Very light and comfortable to hold. There's a definite sense of "modern-classic" in the way the blade emerges from the wa handle. Glue job on the handle still a bit sloppy, and out of the box sharpness is very good, but not phenomenal (global's is better in my experience ), although anyone buying a knife like this should be able to use his/her stones to get it up to whatever sharpness they like. The convexness of the grind does not seem anything like so pronounced as in the YouTube review below - perhaps in response to feedback? The distance between handle and blade is considerable... A matter for personal taste, I imagine - pinch grip comfortable in short bursts, but fingers might need to callus up a little, as middle finger has to rest in that angular space between heel and handle. This, I think, is the major point where buyer must think carefully;as I say,a matter of taste and personal preference, but think carefully. Came with a couple of very minor scratches on the blade... I'm sure after a few years of use these shall be in good company! I like this knife a lot. There is a definite "artisanal" feel to its construction, and I think the shape of the blade (or profile, as they say) is great. For the money, I can't imagine you could do better... If you're willing to shell out another $100 then I suspect this website offers some better, more sparkly options.,but for the measly $150 I paid, it's a bargain. I give this four stars because it is not a perfect knife, some very minor issues with f&f, but if you want better, I suspect you will have to pay to get it!

    This knife is a beaut! Look to me is important. Balance is great and handle is comfortable allowing you to choke up and not loose much length. Glue job was a bit sloppy and is the only disappointing. part

    I have one of your stainless Ultimatums and it is my favorite knife. Although its a bit lighter than the Blazen it replaced, it feels more robust in use. I think it is because the balance is more forward. I really like the balance of the knife and the height and profile of the blade. I have not experienced the wedging some of complained about with the convex grind. For me it just works, works, works. You said on a forum you were proud of this knife, and I agree: Very nicely done!

    Hi Mark,

    I just received my Richmond Ultimatum and I have to tell you it's a beautiful knife, such great steel. The grip of the blade is unbelievable, sliced tomatoes paper thin for a carpaccio, the finishing touches like the rounded spine and finished edge is very good, I couldn't ask for anything more in a knife. Only piece of criticism that I can give ( and it's purely aesthetic) is as beautiful as the handle is the installation could have been a bit cleaner, the glue residue on the entry point is an eye sore in my opinion, maybe is just me but I'm sometimes picky about things like that. The installation point is perfect, the balance of the knife is fantastic, it does not have any effect on the knife whatsoever, im just saying based on the price and comparing other similar knives that I have, I wouldn't expect that from this knife. Anyhow I just thought it would be good to give you feedback on an new item. Thank you again for offering a fantastic knife, It will get much use from me, take care.

    Kind regards,
