Johnson Tools Aven jewelers Coping Hand Saw Frame with 120pcs of Blades and 2 Extra Adjustable Thumb Screws for Jewelry or Other Metal Cutting Works, AC/DC

The media could not be loaded. The build quality of the frame is excellent. The blade used in piercing saw is very brittle unlike conventional hacksaw blades. Just a small bend will break it.The blades should be fixed to the frame along with some tension. Lookup a youtube video on how to attach blades to piercing saw. Or you can follow below steps:1. orient the serated edges of blades similar to conventional hacksaw and attach to bottom side and tighten knob.2. Insert other end of the blade into the upper knob of frame and push frame against something (your body or table as shown in second image) and then tighten knob.3. To confirm the amount of tension, a small flick on blades should give ringing sound(see video)

Product is very good

Tightening mechanism needs improvements, you can't tight the string, so blade gets broken very often, rest all is okay with the product.

Used it for pen nib making, jewellery work and a few engineering projects, saw frame is very comfortable to use and is of great quality. The tool is very good value. Please disregard any reviews about the blades being fragile; theyvare meant to be fragile and will snap if bent too much. If your blades are snapping, either check your technique or check whether you are using the correct blade size for your application.

If there is option for zero star rating would have golden that, very worst product ever seen, not even for single use, just thrown in to the dustbin

Very good product.Only con putting l'll weight ot will be break saw..Saw could be better quality.Othewise work perfectly if gently handle.
