Kunz Replacement Blade for Kunz Plus No. 6

Regular price $59.90

German Design & Construction Make a Great Plane

Even if you do most of your work with machines, you should have at least one useable bench plane in your shop. They are useful for all sorts of situations, especially fine tuning joinery and cleaning up the faces and edges of workpieces. These classic tools make quick work of tasks that would otherwise be difficult and require time-consuming machine setup. Infinity Tools is happy to offer three useful Kunz Plus bench planes that we believe will handle most of your planing tasks. The No. 4 is perfect for final smoothing and refining of your piece's surface before sanding. The No. 5 is called the "Jack" plane for a reason: it can handle jobs where the No. 4 might be a bit too small, and where the No. 6 might be overkill. The No. 6 is technically a fore plane, but it can be used like a jointer for small and medium-sized stock, which is really all most modern woodworkers will ever use it for.

Features:

  • Bodies manufactured from stress-relief annealed grey-cast iron
    • The soles are expertly machined to be flat and square to the cheeks
    • Large cheeks reminiscent of classic Bedrock designs
  • Short and stout, 1/8" thick plane iron
    • Made from optimized tool steel, hardened to RC60-62, prolong life and edge retention
    • Short length leaves more clearance for your hands at the tote and more room for frog adjustment.
  • Classic Features Mingled With Novel Design Innovations
    • Frog rests in a fully machined bed and can be adjusted to open or close the mouth without removing the blade, cap iron, or lever cap
    • Easy frog and mouth adjustment - only one screw needs to be turned instead of three
    • Frog slides in a machined channel that prevents twisting upon adjustment
    • Norris-style adjuster follows the same single-screw adjustment theme as the frog with one point of both lateral and depth of adjustment of the plane iron, with little slop and minimal backlash
    • Brass lever cap screw threads through the lever cap to provide pressure at both ends of the blade and cap iron (aka chip breaker) when engaged
    • Hollow portion of the lever cap screw slides over the protruding part of the cap iron screw, keeping all the components centrally aligned over the cup in the Norris adjuster, and capturing the cap iron screw.
    • Lever cap, cap iron, and plane blade function more like a single solid unit, helping to reduce chatter.
