Generally speaking it's an anticorrosion process. We use the latest chemical process to plate our blades with a micro-thin nickel coating. This is accomplished without the use of an electrical current, so the plating is a very uniform thickness. After being plated, the nickel plating enhances durability of the rust. The plating process produces such a smooth surface that adhesion of tree resins is greatly reduced and if occurs is easily washed from the blade with warm water. As you may know, rust is always a problem with steel products, particularly in humid and coastal areas. Our Special Surface Treatment helps to prevent rust and tarnish.
Rusting is a big problem especially in coastal areas. Many imported timbers contain salts. Cutting such timbers causes blades to rust. Our special surface treatment prevents rusting.
The product name, blade thickness, blade length, and item number of spare blade are indicated on all our hand saws. Even if you lose a package, you'll be able to identify the details of our product. We use a laser to make permanent markings on the blade.
The cutting edge is heated for 0.003~ 0.005 seconds by applying an electrical current at 27.12MHz. This creates a shock wave on the surface of each tooth that hardens it to Hv900~1200. For comparison, sharpening files are only hardened to Hv800~ 850.
If heating is done multiple times on each tooth, the heating quality varies and it not only hardens the surface of each tooth but also the core. This causes tooth to chip.
1. We use specially developed impulse hardening machine to make long lasting blade.
2. We heat each tooth just once instead of multiple times.
3. For better flexibility, we only harden the surface of each tooth.
This makes the surface of each tooth very hard, but still keeps the inside core flexible. This is the key to blades with longer life.
Wrapping the handle with rattan makes the handle stronger. Also there are tiny spaces in between the handle and the hand, which prevents sweating and slipping. Rattan wrapped hand saws are traditional hand saws. The whole handle wrapped with rattan is considered better quality than partly wrapped handles.
Elastomer resin on the handle.
Our EVA grip is light and soft, which reduces the stress on the wrist. It also prevents slipping even if your hand becomes sweaty.
The screw is embedded in the handle, so you can replace a blade even more quickly. Since the screw does not come off, you do not need to worry about losing it when replacing a blade.
EG grip is just 59g, so it reduces the stress on your wrist while working. You don't need a driver to replace a blade.
Beech wood that we use on our handles are those used for making furnitures and instruments.
Painted handles are strong against humidity. It fits perfectly in your hand, and it also prevents slipping.
We use magnolia wood for Megumi series, cherry wood for Plant Hunter Mini, and white oak for Kami no Utsuwa.
Since you can put it on your belt, it's especially recommended for outdoor use such as for landscaping and working in fruit farms.
Folding saws can be safely stored in your tool box. Folding saws are recommended for people who don't use the saw frequently. Opening angle can be adjusted. Folding saws for both outdoor use and indoor use are available.
Hand saw with a straight handle for indoor use. There are single edge saws, double edge saws, and folding saws. There are also hand saws with a sheath for outdoor use, pole saws, and small cutter saws.
They have a grip like cutter knife. It's sometimes not so easy to carry around a big hand saw. Our cutter saws are small enough to fit in your pocket. It will be perfect when you have branches that're too big for your pruners, but not that big to use a regular hand saw. Please pull the whole blade out and make sure to tighten the screw when you use our cutter knife.
You will have a brand new cutting edge by replacing to a new blade. We mark item number on the spare blade. Please check the number on your hand saw when purchasing a blade.
All our hand saws except for flush cutting saw single edge and double edges have replaceable blade. These two items do not have a replaceable blade since there is not much difference between the whole saw and just the blade itself.
Some of our hand saws don't come with a sheath. This way we set the price more economical. You could put your saw back in the plastic case for better storage.
The length of the blade should be based on the length of the stroke you make with your arm when you use a hand saw.
In general, the ideal blade length is 240mm to 270mm. People with more experience make big strokes and use the whole blade, but people with not much experience tend to make small strokes.
We offer hand saws with blade length shorter than 240mm. These are especially suited for household use and for the beginners.
