Premium Sit-Flat Naked Portafilter
Regular price $150 USD $
Regular price USD Sale price $150 USD
Handle Material | Rubber Handle Material


The BUCK™ is a naked portafilter crafted from a block of forged, machined, and polished stainless steel. Much like the Unifilter, it is designed to sit flat on a countertop, eliminating the need for the awkward hanging-off-the-edge-while-tamping of standard portafilters. Available in 2 styles of handle, both the FKM Rubber and Solid Teak handles have a solid stainless core which gives it the heft and strength to last a lifetime. While optimized for use with any Unibasket™ size, the BUCK will work with all standard 58mm baskets.

Availability & Delivery

Our next batch will be ready for sale and immediate shipping in early April 2024. 


The BUCK™ is a crafted from a block of forged, machined, and polished stainless steel. The handle core is solid stainless and runs the length of the handle. 


All handles have a solid stainless steel core to give them heft and longevity. That is covered either by a thick FKM rubber sleeve, or a cored-out solid piece of solid teak wood sanded and finished with a non-VOC oil that will patina over the years like a piece of fine Danish furniture. They are both built for life.

Included in package

  • 1 BUCK, with either FKM Rubber or Teak handle.
  • 1 Portafilter retention spring, optimized for Unibasket™


  • Fits standard 58mm portafilter groups incorporating E61 design with exposed group, including:
    LaMarzocco (all except Micra and KB-90), Slayer, Synesso, Kees VanDer Westen, Decent, Flair 58, etc.

Victoria Arduino Compatibility Note: The BUCK is compatible with VA machines, however it locks in significantly to the right of center.
