Marianne Halpern of Three Rivers Manufacturing (TRM) joins Bob "The Knife Junkie" on episode 240 of The Knife Junkie Podcast.

TRM's parent company, Halpern Titanium, Inc. began selling supplies to custom knife makers from the Marianne's and Les' kitchen in 1997. Halpern Titanium bought a CNC in 1999 to machine knife scales for knife factories worldwide; 23 years later, Halpern has grown into a fully-fledged knife manufacturer.

Three Rivers Manufacturing manufactures TRM and private label knives with waterjets, wire EDMs, Swiss lathes and numerous CNC machines and grinders of all types. Almost all TRM knives are constructed for easy changeability of handle scales. The company manufactures and sells scales in a multitude of colors and materials for most models.

TRM's latest model called Shadow, is a larger locking version of their Nerd model and is built around their River-Lok, their take on the Axis Lock.

Due to the more complex construction of the Shadow, changing scales is not as easy, so TRM offers changeable filler tabs for off-side milled clip pockets.

You can find TRM online at www.threeriversmfg.com (https://www.threeriversmfg.com), on Instagram (https://www.instagram.com/t_r_m_3rivers) and on their private Facebook group (https://www.facebook.com/groups/1227424600677967).
