What's In The Box.
FAQ
Check out the most common questions our customers asked.
What makes the KM-19 different from a standard hardware store coping saw?
The KM-19 is built with a high-rigidity aluminum alloy frame and a unique lever-action tensioning system. Unlike traditional saws that rely on twisting the handle to apply tension, the KM-19 uses a mechanical lever that provides significantly higher blade tension, resulting in cleaner cuts and less blade "wandering."
Does the KM-19 use standard coping saw blades?
Yes, it is compatible with standard 6.5-inch (approx. 165mm) pin-end blades. This allows you to use your favorite third-party blades (like Pegas or Olson) for different materials and tooth counts.
How do I adjust the blade angle?
The KM-19 features a 360-degree rotating blade holder. To adjust the angle, you simply rotate the thumb-adjusters at the front or rear of the frame. The indexing mechanism ensures the blade stays locked at the desired angle during the cut.
How much tension should I apply to the blade?
You should apply enough tension so that the blade emits a "ping" sound when plucked, similar to a guitar string. The KM-19’s lever system is designed to handle high tension, but you should always release the tension lever when the saw is not in use to prolong the life of the frame and the blade.
The blade rotation feels stiff. How can I fix this?
Over time, fine sawdust can enter the rotating assembly.
1. Release the tension lever.
2. Remove the blade.
3. Clean the rotating hubs with compressed air or a soft brush.
4. Apply a single drop of light machine oil (3-in-1 oil) to the rotating interface. Do not use heavy grease, as it will attract more dust.
Can I use this saw for metal or plastic?
Yes, provided you install the appropriate blade. While the KM-19 is a favorite among woodworkers for clearing dovetail waste, its rigid frame makes it excellent for precision work in thin non-ferrous metals and plastics when paired with a high-TPI (teeth per inch) blade.
Why is my blade snapping frequently?
Frequent snapping is usually caused by one of three things:
1. Over-tensioning: While the saw supports high tension, exceeding the blade's physical limit will cause failure.
2. Aggressive Turning: Trying to turn the saw at too sharp an angle while moving too fast puts lateral stress on the pins.
3. Heat Buildup: In very hard woods, friction can overheat the blade. Slow down your stroke rate and let the teeth do the work.
The tension lever feels too hard to close. Is something wrong?
Check if the blade is properly seated in the pin slots. If the blade is slightly too short or incorrectly positioned, the lever will meet excessive resistance. Never force the lever; ensure the blade pins are fully engaged in the hooks first.

This is the last Coping/ Fret saw I will ever need. Verry Verry nice!!
Another high quality product from Hongdui and JKM
What a joy it is to use this coping saw.
It's very well made from super premium materials. It feels really good on hand and the adjustments, settings are very easy and intuitive. It took me a bit of a trial and error to figure out how to install and use the pinless saw blade., I recommend Katz-Mozes YouTube video on this tool to really familiarize yourself.
It's very easy to get a super tight tension on this saw and best part is the ability to easily rotate the saw angle in 45 degree increments to start sawing sideways inside the dovetails or other joints.
I am extremely impressed with the quality of this saw. It is extraordinarily well machined. I don’t own a lot of hand tools that are this well made. My primary use for this saw is to cut brass rods using jeweler saw blades. This saw allows you to easily change blades and takes both the traditional coping saw blades as well as the jeweler wire style blades. The design of this saw allows you to get a great deal of tension on the blade due to its rigid frame (it’s possible to over tension, so be aware of that). For setting the blade angle there are indexed stops every 45 degrees, and the blade holders are hex, so they are naturally indexed every 60 degrees which makes alignment a little tricky, but once you have the two indexes set and the blade holders inserted it’s very easy to set the angle of the saw blade, though 98% of the time I’m using it set inline with the saw frame. Two of my pictures show the index marks mentioned in the instructions vs the blade holder position. It would have been nice if the index mark lined up so that the blade was inline with the saw frame when the index marks showed through the window, though this is really minor. This is an expensive saw, no doubt, and that cost is certainly justified by the high quality machining and finish. This is really a beautiful tool.
This is one of the best tools for dove tail work, hands down. The blades are small enough to fit down the narrow kerf of a dove tail saw and clean out the waste properly. Well built, excellent design.
Totally lived up to its reputation. Well build and easy to use.
Not used yet, but gives a very high-quality impression. I am sure I will enjoy it.
The product is exactly as described, It took less time to arrive than announced.
very well made and design is excellent highly recommended buy thanks
looks fantastic,a true masterpiece of a saw.
