Our in-depth range review

First Impressions


We'll come onto beauty in a moment, first off this is without doubt an impressively sharp knife right out of the 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


Depending on your preference, the lighter wa handle knives in this range tend to have a balance point close to the heel of the knife while the heavier full tang yo handles are certainly more significant in hand an that balance point sits further back.

Durability


There are two versions of the rainbow damascus knives (we also stock the carbon steel aogami) and the VG10 is a strong alternative offering a good level of edge retention and durability much like the carbon steel and it's a popular choice for a lot of blacksmiths because it's easy to work with and offers a durable and reliable cutting edge.

Ease of Care & Maintenance Tips

This version of the rainbow damascus is easy to look after and maintain thanks to the stainless VG10 core and cladding so 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 prefer a carbon steel, check out the aogami 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 the box and start using it. 

Saji-san is a master blacksmith and these knives show attention to detail, sensational style and blade geometry across the range that performs at a high level and so while they're certainly showy thanks to that incredible subtle rainbow damascus - make no mistake, this is a high performance line of knives.
