Saya de madeira para Santoku [bainha de faca] - 190mm (7,5")

Hello,

Urban from SharpEdge here — thanks for your feedback.

There is still a lot of manual work involved in making Japanese knives, so there may be slight variations in the dimensions of the blades. I tested knives of the same model as you have at home and inserted them into the same wooden santoku sayo. Some of them fit, but in others the pin did not fit properly. This is a consequence of the handmade nature of the knife, where not every knife is exactly the same as the other.

On the product page (knife), we have written which sayas fit each model. For this knife, we did not list the sayas because unfortunately it does not fit every specimen. Usually, we check the suitability of each saya when sending it, but in this case we clearly missed it.

We will contact you via email with the next steps to resolve the problem.

Best regards,
Urban

Thanks for your review, Greg. Indeed, our saya has a slightly looser fit on smaller blades. I tried it on a few of the 165mm santokus we have in our shop, and there is a small wiggle, but nothing out of the ordinary. There should be a slightly loose fit on wooden sayas, otherwise the blade hits the edge of the saya every time you insert the blade or pull it out. This will dull the blade, so the looser fit is there by design.

If you can send us a video of how loose it is, it will be easier for us to help you out. In the end, it all comes down to the width of the blade on your santoku. It could be you have a narrower model or have a used knife that's been sharpened a few times which would make the blade narrower and thus a looser fit.

Thanks,
Urban
