Our aim is to measure and photograph all our products as accurately as possible but due to the handmade nature of many items, please be aware that there may be some variance in the measurements and that things such as blade and knife handle patterns can vary and presentation boxes may differ from those shown but we will always endeavour to provide the most accurate measurements, photos and descriptions of our products.
Some measurements such as HRC are provided by the manufacturer and should therefore be used as a guide.
Protection & care for this knife

Due to the height of this knife, we do not currently have any wooden or leather saya to fit and recommend a petty sized blade guard.
