Dozuki (backsaw) range of saws

Dozuki - the finest traditional Japanese saw with the extra thin blade supported by the long metal spine has been an essential in the arsenal of all professional cabinet makers, temple builders, furniture restorers etc. for centuries.

All the saws in this range have blades which are an incredible 0.3mm thick (although the kerf is slightly greater). The difference between these and more conventional blades can be seen clearly in the picture below. A thinner cut means less waste, less effort in cutting, less heat generated and less sawdust.

Blades for long-backed handles come in 2 lengths: 150mm and 240mm. Whilst all the 240mm blades can be freely interchanged in the same handle, and the same for the 150mm blades, they cannot be used in the other size of handle.

The choice of size is a personal one. The smaller saw is perhaps better for modelling and very fine work, although the larger saw can also be used in the same situations.

150mm blades

H-150 Dozuki
This is the finest wood blade in this series with 25 TPI and is really a joy to use. It copes with both hard and softwoods and is great for dovetails and other jointing work.

H-150 Dozuki hardwood
A fantastic new saw for use with hardwoods. Slightly coarser at 21 TPI but really excellent on woods as hard as ebony. The Instagram review below by the London School of Furniture Making and the video are both of the 240mm Dozuki hardwood saw rather than the 150 mm blade but the tooth pattern is identical.

H-150 Panel piercing
This saw has a slightly coarser tooth pattern again, at 18 TPI, so cuts a little faster. It is therefore very useful for more everyday cuts where extreme fineness of cut is not required. It also has little secret in the "woodpecker" tooth at the front of the blade which a allows a cut to be started in the centre of a panel.

There is another video further down the page showing the larger (H-240) piercing saw in use.

H-150 Handy Craft saw
Designed for use with soft metal (lead, copper and aluminium), plastic and wood, this is a great hobby saw. With 28 TPI it leaves an exceptionally smooth finish.

Although all the H-150 blades will fit either of the handles shown, the shorter handle is only available with the Handy Craft blade: once you have bought this complete saw you can add any of the other blades.

240mm blades

H-240 Dozuki
This is the finest blade in this series with 25 TPI and is really a joy to use.

In fact I recommend you don't leave it lying on your workbench or you are likely to find yourself using it even when an ultra-fine finish is unnecessary!
There is also a slightly wider Dozuki blade with the same incredibly fine tooth pattern, the H-240 Dozuki Wide

H-240 Dozuki hardwood
A fantastic new saw for use with hardwoods. Slightly coarser at 21 TPI but really excellent on woods as hard as ebony. The Instagram review below by the London School of Furniture Making and the video are both of this blade.

H-240 Panel narrow, H-240 Panel wide and H-240 Panel piercing

With 18 TPI these 3 blades are good for everyday woodworking where extreme fineness of cut is not required (and they are much cheaper than the Dozuki blades). The piercing blade also has a "woodpecker" tooth at the front of the blade which a allows a cut to be started in the centre of a panel.
The video below shows the piercing saw in use.
