Quick verdict
If you want a manual shear for bench work and your material isn't too heavy, the KAKA Industrial HS-12 is a practical option at USD 157.00. It's a manual, workbench-mounted 12-inch throatless cutter with 6 mm sheet steel capacity, plus 13 mm round steel and 70x6 mm flat steel capabilities. For a shop that needs a no-frills shear, the HS-12 covers a useful range.
Who it suits
The HS-12 suits anyone who cuts sheet metal regularly but doesn't need the speed or force of a powered shear. It's also a good fit for a small workshop bench where a hand-operated cutter is enough. Manual control means you set the pace and pressure on every cut.
What stands out
KAKA Industrial HS-12 Throatless Shear

The 12-inch throatless design is the headline feature. It gives you open access around the blade, which is useful when positioning sheet metal. The workbench mount keeps the shear steady, and the 305 mm blade is a match for the 12-inch class.
The cutting capacities are the real decision point: 6.0 mm sheet steel, 13 mm round steel, and 70x6 mm flat steel. That flat steel spec is handy if you trim strap or bar stock. One concrete reason to choose the HS-12 is that it packages these capacities in a manual shear with a throatless layout. The trade-off is that you supply all the force, so long cutting sessions or heavier-gauge jobs will be tiring.
Meaningful trade-offs
The biggest trade-off is manual operation. Because the shear is manual, consistency depends on your strength and technique. The workbench-mounted design also means you need a stable surface with enough clearance. If most of your work is oversized panels or thick plate, a manual shear like this may fall short.
Bottom line
Choose the KAKA Industrial HS-12 if you want a straightforward manual shear for bench work and your projects stay within its stated capacities. For about USD 157.00, you get a 12-inch throatless cutter with a 305 mm blade and 6 mm sheet steel capacity. It won't replace a powered shear, but for light trimming and small fabrication, it's a solid addition to a metal forming setup.
