Cutting steerer tubes, seatposts, and handlebars to length is one of the most common shop tasks, and a sloppy cut means a bad fit or a component you can't use. Park Tool's SAW-1 Hacksaw is built around a die-cast aluminum frame that holds the blade rigid under tension, which is what keeps cuts straight and controlled. The rubber-padded handle absorbs vibration and gives you a solid grip through repetitive strokes, so you're not fighting the tool while you work.

The SAW-1 ships with a 12" (300mm) steel blade at 32 TPI, which is the right tooth count for thin-wall bicycle tubing in steel, aluminum, or titanium. The fine pitch reduces the risk of snagging on tube walls and keeps cuts cleaner than a coarser blade would. If you need to cut carbon fiber components, the SAW-1 accepts the CSB-1 Carbon Cutting Saw Blade, which uses a tungsten carbide grit edge that abrades through composite material instead of tearing it. That blade is sold separately, but it drops right in with no adapter needed.

Because the SAW-1 uses standard 12" hacksaw blades, you're not locked into a proprietary system. Any 12" blade from any manufacturer fits, so you can swap to whatever TPI or tooth profile a specific job calls for. Pair it with an SG-8 or SG-7.2 saw guide for repeatable, square cuts on steerer tubes and seatposts, and you've got a setup that handles the full range of cutting work in a bike shop or home workshop.
