Planer knives
for your joinery workshop –
Clean cuts over long tool lives

As a master joiner, you know:
A perfect planing finish is your calling card. But do you also know how much money you lose every year with a poor-quality knife? BARKE TriMetall® knives last 30-50% longer than standard knives and deliver a consistently clean result from the first cut to the last.

The decisive loss of performance occurs unseen

The quality of a planer knife does not drop off suddenly, but gradually. Long before differences in the planing finish become visible, the knife is already losing its sharpness and thus its efficiency. Many businesses rely on subjective judgement to determine when to change their knives: once the surface quality begins to decline and the finish no longer appears clean enough. This is exactly where unnecessary costs often arise.

High-quality knives stay sharp longer. This increases the tool life, reduces change intervals, and ensures consistently clean results.

* Calculated using actual BARKE unit prices (2026). The stated tool life advantages (30–50%) are based on experience from customer surveys and internal comparative tests. Actual tool life is affected by wood species, feed speed, machine condition and cutting hardness. Assumed changeover time: 30 min for solid planer knives and 10 min for reversible knives. Your individual savings may vary.

  • It takes time: 15–30 minutes per change
  • It costs money: €5–€10 per knife for the sharpening service
  • It costs productivity: The machine is idle

These hidden costs add up.
And this is exactly where BARKE comes in.

The solution: TriMetall® technology with HSS-M42 cutting edges from BARKE.

Standard knives compared to TriMetall knives

BARKE TriMetall® knives consist of three layers: a soft middle section made of easily profileable steel — and two cutting edges made of ultra-hardened HSS-M42 material. In addition, a mirror-polished bevel ensures a significantly better planing finish.
