When rebar reaches a 16 mm diameter, cutting it isn't just a matter of force, but of the right technique and superior equipment. The Yakar 16 mm Rebar Cutting Lever Shear is the zenith of manual tools, designed for the most challenging sites where electric cutters can't reach, generators can't be transported, or there's a risk of sparks.
This article discusses the technical details and intricacies of using this product for professionals seeking maximum capacity in manual cutting.
Product Description: Why So Big?
The Yakar 16 mm shear is the largest in its series. Its total length can typically reach 1 meter 20 centimeters (48-inch class). This enormous length is not for show but a physical necessity. To generate the tons of pressure required to cut 16 mm thick steel, it features a giant lever system that multiplies the user's applied force by at least 50-60 times.
Material and Durability Technology
This shear stands apart from standard hardware materials. The load it carries is so immense that ordinary steel would bend or break instantly. Yakar uses top-tier metallurgy techniques in this model:
Special Alloy Forged Steel Jaws: The cutting head is produced from hot forged steel as a single, monolithic piece. This eliminates air pockets within the metal and increases its density.
Zonal Hardening: Not only the cutting edge but also the neck part that bears the load undergoes special heat treatments. The cutting edges are induction hardened (58-62 HRC) to maintain their form while crushing rebar.
Heavy-Duty Handles: The shear handles are made from thick steel pipes, making bending impossible.
Reinforced Hinge System: The connecting bolts and plates are extra reinforced to withstand the enormous stress created during cutting.

Areas of Use and Sectors
The 16 mm shear is not a tool you'll see in every craftsman's hand at a construction site. It's used in special situations and heavy industry.
Critical Areas of Use:
Infrastructure and Heavy Construction: In the initial setup phases of bridge, viaduct, and dam construction sites where power lines are not yet installed.
Earthquake and Search & Rescue: Vital for creating life corridors by cutting thick column rebar in situations where fuel-powered or electric cutters cannot be used (due to noise and gas risk) in rubble.
Mines: In underground galleries with a risk of firedamp explosions, tools that produce sparks (like angle grinders) are prohibited. The Yakar shear is the safest solution as it performs "Cold Cutting."
Port and Shipbreaking: Cutting thick chain links and ship ropes.
Railways: Cutting rail mounting elements and thick studs.
Important Warnings and Techniques for the User
How to Use? (Body Weight Technique)
Attempting to cut 16mm rebar with arm strength alone can lead to injury. The correct technique is as follows:
Lay the shear on a flat, solid surface.
Place the rebar to be cut at the deepest point of the shear jaws.
The user stabilizes the lower handle by stepping on it with one foot, then presses down on the upper handle with the other foot or their entire body weight.
Risk of Flying Debris: When 16 mm steel breaks (snaps), pieces can fly off with a shrapnel effect. Full-protection safety glasses and steel-toed boots are mandatory.
Capacity: Never attempt to cut hardened steel (e.g., axle shafts, hard spring steel). This shear is only for soft rebar.
Maintenance
To extend the life of such an expensive and critical tool:
Blade Adjustment: Ensure the cutting blades close completely. If there's a gap, tighten the adjustment bolts.
Spare Parts: Yakar's biggest advantage is the availability of replacement blades. You can use the body for years by replacing dulled blades.
