Our in-depth range review

First Impressions

The fit and finish are definitely a good standard and the sharpness out of the box is already impressive.

Should you wish to, you could thin it a little further to really bring out an additional level of sharpness but right out of the box it's a nimble and reasonably light knife that's a joy to use.

Beauty

The range comes in a variety of options including both kurouchi and unpolished finishes and with a wa handles made from burnt oak, cherry and morado wood or Western yo shape red pakka wood.

The tsuchime hammer finish tapering down to expose the aogami super core along the cutting edge and engraved kanji combine is subtle and each blade is uniquely patterned.

In Hand

A smooth fit and finish on the wa and yo handles and well balanced it's easy to use although if we were being really picky we might have liked a slightly smoother finish around the heel/chiol where you might find it a little rough but it doesn't significantly impact on overall comfort or use.

Durability

The stainless clad aogami super should retain its edge well and it's reasonably easy to maintain and sharpen so the knife will last as long as you want it to and perform time after time.

Ease of Care & Maintenance Tips

The aogami super steel along the cutting edge is reactive and will develop a lovely patina as it reacts with your food and moisture but apart from the normal care instructions it's a nice easy knife to keep.

Our Verdict

At this price point, the Tsunehisa AS is unquestionably a great value Japanese knife.

You're getting a well made knife with an Aogami Super steel core and a nice selection of both handle and either unpolished or kurouchi finish and they're impressively sharp and ready to go right out of the box.

If you're looking for an AS steel, we happily recommend the knives in this range.

Great introduction to Japanese knives

This knife feels amazing in the hand and cuts very smooth. Pretty sharp out of the box, but after less than 10 mins on the whetstone/strop it is one of the sharpest I have ever used. The super steel keeps the edge for a long time, and I think it is one of the biggest selling points of this knife, especially for the price.

Beautiful craftsmanship

A light, excellently balanced knife. The length may look intimidating, but it handles so well and easy to use especially for long smooth slicing ingredients. I find it a real pleasure to chop veg because the length puts the pivot point further away giving me more control and the thinness, sharpness and smoothness of the blade just slides through ingredients.
There are definitely benefits to a longer blade knife of this quarter. Now the go to knife out of the 6 japanese knives that I own.
