choosing the proper Swanstrom tools
Different cutting edges and length determine the required squeeze pressure,
shock, and the amount of "pinch or spike" left on the wire.
Prominence of the spike or cut wire line is a function of:
- jaw, bevel, and
cutter edge type as new (angles of jaw (<j), of hone (<h), of
bevel (<b), and amount of bevel)
- the edges' past
use and current condition
- the joint's past
use and current condition
- the material, hardness,
and diameter of wire cut
edges are used where "pinch or spike" left after cutting is not critical
and where shock transmitted will not damage parts or components. Bevel
edges optimize the number of cuts over the lifetime of the cutter, but
require more pressure to make cuts.
reduce shock transmittal, lessen pinch, spike, and squeeze pressure.
edges should be specified when requirements call for minimal spike and
very minimum shock transmittal. They are more ergonomic and require even
less squeeze pressure than full flush. Full Flush edges have .002 bevel.
Super Flush, Super
Sharp edges are the most ergonomic and easiest to squeeze. Available
option on various wire cutter. Special order required.
reduces force required to cut. Rather than a spike there will be a slight
side deformation and step left on the cut leads.
give easiest cuts. The end of the sheared wire has no spike, just a small
side deformation. Some cutters have notches for stripping insulated wire.
If stop is set for blades to bypass, stranded insulated cables will shear
with little deformation.
cutters minimize shock, leave no spike and can give consistent "stand
off" lead lengths.
Even Super Flush
cutters will leave a visible line, for the wire is ultimately separating
by tensile failure, not knife cuts. Sharper options mean easier cuts and
lesser wire spikes, but also somewhat shorter edge life.

(Diagonal Cutter) Head shapes are oval, taper, oval slim, and taper slim.
Each option brings a finer point and ease of access in tight places, but
also increases the risk of tip breakage due to the smaller cross sections
near the tips. A user has trade-off choices between long edge-tip life
with a more blunt (oval) nose, and the finer edge - tip design (taper
slim) with greater risk. Confines of the work often dictate the finer
points. Tools used within specified limits cut the risk to nearly zero.
Back .125" from tips, taper slim cross sectional area is only 53% that
of the oval head. Users can save money by specifying oval head tools if
confined areas don't dictate otherwise.
Cutter Edge Lines
For electronic use, most work is done at the tips and cutters are honed
for max life at the tips. While holding cutter lightly closed you should
see an increasing amount of light from the tips back toward the crotch.
This optimizes life of tip cutting tools.
Long Nose and Needle
Nose Tips and Edges
Electronics industry needs the small tips for intricate work. Tips vary
on the different types and styles. Beveled edges are standard on smooth
jaws. Special radiused edges to meet Mil Specs are available by adding
the suffix "SR" to the part number.
(available on most diagonal cutters) hold cut leads from flying or falling
into critical work areas. Thin design offers good visibility and cutting
