Saw frames. They’re one of those tools that have always been around. Have you ever given them much thought? At first glance, one looks very
similar to the next. But, there are several features that you should consider before purchasing a saw. Whether you’re new to sawing or you’re a
seasoned pro, there are several options available to you. Here are some terminology and descriptions that will simplify your decision:
Throat Depth
Throat depth is the measurement from the handle of the frame to the
back of the frame. When selecting the throat depth, consider the size of
the material you’ll be working with. The depth needs to be long enough
to accommodate the width of your sheet, but it shouldn’t be deeper
than necessary. Remember that the deeper the frame, the more flex it
will have. And the more the frame flexes, the less control and the more
broken blades you’ll have.
Frames that are
adjustable help you make
minor adjustments to the
blade’s tension. Typically,
most jewelers use the
frame adjustment as a
secondary way of adding
tension to the saw blade.

Blade Holders
There are several styles of blade
holders or clamps. One of the
most common is a serrated clamp.
The inside edges of the clamps are
serrated to achieve a good grip
on the blade. The clamps are held
tightly with wing nuts. Our Swiss
adjustable saw frames (page 99)
feature a patented blade-locking system. The saw blades
are inserted into holes at the top and bottom of the
frame. The locking nuts on the outside of the frame screw
in and hold the blade tight and true.
The Knew Concepts frames (page 100) have a blade
holder with a tensioning system built in. The blades
are inserted into the blade holes and tightened down
with thumbscrews. At the top of the frame, there is an
adjustment knob that is used to give your saw blade
the exact tension you need. The blade holder and
tensioning system is perfect for anyone who does
a lot of sawing and piercing.
