When I confronted my first wood working jobs here I was quite surprised that many Japanese hand tools were totally different to the tools I was accustomed to using. Hand saws I found difficult to adjust to the most, now I would not even contemplate using anything else.
Japanese saws cut on the pull stroke rather than the push, this gives the carpenter some major advantages which at first glance are not immediately apparent. The first and foremost being the saw blade is considerably thinner, simply because it does not have to resist the thrust of a push stroke cut. Secondly, accuracy is dramatically improved as cutting on the back stoke is far easer to control. You may very well think as I did these would be slower and harder work to use, when in fact they are faster.
I would recommend any one that can get their hands one to try them.
Yes that is true, but these saws are for general woodworking and have the added advantage of being double edged, one edge for cross cuts the other for rip cuts. The ah! ah, moment is in understanding just how a saw works or any other tool for that matter, therein is the secret, along with an understanding and a feel for the material being worked.
