Carefully selected by a famous Japanese carpenter. The blades of these particular saws are replaceable and are held securely in the wrapped handle by a simple screw. One edge has teeth for ripping, with smaller teeth near the handle to use when starting the cut, before bringing the full effective edge to bear on the workpiece. The other edge has crosscut teeth which produce a wonderfully clean cut surface. The centre of the blade is scraped to be thinner than the edges so as to prevent binding in a deep cut. The word 'replaceable' might conjure up an image of a mass produced item. In actual fact every blade is checked and hand finished before leaving the manufacturer. These saws are made for the professional Japanese market so there is no compromise on quality. Two sizes are available 195mm and 240mm, the longer of the two having slightly coarser teeth. Tpi is not really relevant in this case, the heavier the work the longer the saw, either of these offered here suit the vast majority of tasks.
- It's a kind of magic Review by John Adams - Permaculture magazine
What to do? This was quite an expensive, solid oak piece of furniture, that matched the rest of the bedroom. We rang the furniture shop, who confirmed there wasn't a smaller one, and also advised against my first idea, which was to try and disassemble it. The choice was to take it back for a refund and give up, or rather more radically, to cut it in half and move it in two bits. I have plenty of power tools which could have chopped it up in seconds but I knew that the result would be less than satisfactory from a visual point of view and would almost certainly remove too much wood, which would result in the draws sticking.
Having used it on a couple of other fine woodworking jobs, I was fairly confident that I could cut the chest of draws in half laterally using my Japanese Ryoba hand saw, with minimal damage. Easier said than done of course, though it was actually very straight forward. First I carefully measured round the chest of drawers and then joined the marks using a large sash cramp as a straight edge. Then I check measured it, and sure enough it was wrong. The old adage measure twice cut once, saved me again.
Now for the cut, the Royba saw has a thin flexible blade on the end of a straight handle. The blade has very fine teeth on one side and slightly courser ones for fast cutting on the other. Despite having a very long cut to make, I chose to use the finest teeth to get the least noticeable cut possible. My son couldn't look as I took a saw to his brand new £400 piece of furniture and went and did another job upstairs. Actually it went very well, once I stopped agonising over whether I was keeping the saw perfectly aligned in all planes, and settled into a steady rhythm.
And the result was almost perfect, when we put the two halves on top of each other upstairs, the join was almost imperceptible and certainly nothing a bit of furniture polish wouldn't hide. The drawers still worked perfectly, a testament to the fineness of the cut which removed no more than a mm of thickness. My son decided to fit some metal plates on the inside to keep the two halves together, rather than gluing it, so it can be dissembled if he ever decides to move.
All in all, a bit of a magic trick, very like sawing the lady in half, but with a much more permanent and pleasing result.
