First Impressions

We'll come onto beauty in a moment, first off this is without doubt an impressively sharp knife right out of the (wooden) presentation box and looking down the choil you can see a quality and consistent flat grind which will work efficiently and make clean cuts time after time. 

Beauty

Obviously a large part of the magic of the rainbow damascus is its visual appeal and it definitely doesn't disappoint on this front. 

The layering running along the full length of the blade is created by alternating layers of brass and copper which form a cloud like pattern along the top of the blade and then switch to running the full length of the blade. 

Aesthetically, the rainbow damascus is a stunner.

In Hand

A lot of Takeshi Saji knives are fitted with fairly big and quite heavy full tang handles which aren't for everyone so this limited edition is fitted with a more typical octagonal wa handle which takes a little of that weight out of the knife, moves the balance point forward a fraction and contributes to a nice and nimble feel in hand. 

Durability

A traditional Aogami #2 core clad in stainless is widely used because it's reliable and gives you the durability and edge retention of carbon steel and an easy to look after cladding with the brass and copper layers woven in between. 

Ease of Care & Maintenance Tips

Just follow our normal care instructions, wash and dry after use and show off your knife when you're not using it by storing it on a magnetic rack or block!

If you'd prefer a fully stainless version, check out the VG10 rainbow damascus range.

Our Verdict

The rainbow damascus is a wonderful knife, it's beautifully made and presented and we have no doubt you'd be very happy when you open that wooden presentation box and start using it. 

In terms of absolute value for money, it's not unreasonable to say that because you're buying a limited edition knife made using quite a difficult technique this does form a part of the overall price but there's a reason people seek out and buy Takeshi Saji's knives and collect his work and so for the cook who's seeking that something a little special - this is one of those collections!

It's a piece of highly functional art you will love looking at as well as using.
