The Science and Making of CPM 154 Powder Sintered Knives with David Rydbom
Rad video from In The Making profiling David Rydbom aka kingdomarmory and his custom, world-class handmade knives:
Doc North pays David Rydbom of Kingdom Armory to see his home shop where he makes eye-catching collectible knives. At the heart of the Unagi knife is a sintered alloy. Dr. North takes you on a deep dive into the science of sintering to understand how these high-performance materials give a balance of hardness and toughness. And see how Dave creates these knives with a modest shop.
You can read the datasheet for CPM 154 here. And check out a few samples from kingdomarmory’s Instagram feed below.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
