Why a ratchet-lever clamp instead of a clutch or screw clamp
A ratchet-lever clamp builds pressure in controlled steps with repeated lever pulls, similar to a ratchet strap — you feel each increment of pressure rather than sliding a jaw into place and cranking a screw. That incremental feel is the main reason woodworkers reach for a ratchet clamp over a clutch-style or screw-driven one: it’s easier to stop the instant you feel resistance, which matters on delicate glue joints or assembly work where over-tightening can shift or damage a piece.

The Bora reaches further (12" vs 8") and is rated for more force (330 lb vs 260 lb), which makes it the more capable choice for general glue-up and assembly work where you need both more force and more reach. The Bessey KliKlamp’s magnesium construction and non-marring plastic caps are a lighter, more delicate-handling option for smaller work where minimizing weight and avoiding marks matters more than maximum force or reach.
Bottom line
Both are ratchet-lever mechanisms, not two sizes of the same product — pick based on whether you need the Bora’s extra reach and force, or the Bessey’s lighter weight and non-marring jaws for smaller pieces. Bora 571012 and Bessey KLI3.008 KliKlamp .
