The LENOX High-Tension Hacksaw uses a special I-beam construction that allows blades to tension up to 50,000 psi, resulting in fast, straight cuts. The rubberized handles allow for confident handling, even in wet and cold environments. The LENOX hacksaw accepts any LENOX reciprocating saw blade for use as a jab saw and can also store up to 5 extra 12-inch hacksaw blades in the I-beam. All hacksaws come with one 12-inch, 24 TPI hacksaw blade for immediate use.
