Our Business

Our knife scales are CNC machined out of high quality billet aluminum, at United Precision Machining, right here in America. This process ensures a precise and consistent finish, providing both strength and a sleek modern look. Our aluminum offers excellent durability, making out knife scales a very reliable choice for everyday use. Our gun grips are 3D printed at Kave Monkeyz, using crushed carbon fiber mixed with a little of nylon for flexibility. This material and process combined, produce gun grips that are incredibly strong and light weight. The crushed carbon fiber construction provides superior durability, and a comfortable, secure grip, enhancing both performance and control.




I was born in the beautiful state of Wyoming, in the town of Sheridan. Where my mother and father had a custom cabinet shop. Dad taught my 11 siblings and I perfection, quality, and art through building gorgeous cabinets, and the houses we remodeled. I spent a lot of time working with dad, hunting, fishing, and camping in the mountains. As I graduated high school, I found a love for CNC machining. My older brother was in the trade, so I moved to Minnesota to learn and work with him. I then went home and got my associate degree in cnc machining, and moved back to Minnesota to again work with my brother. I soon met my wife here, and now have 2 amazing children.
In the fall of 2019, I decided to move forward on opening my own company. In January of 2020, Kave Monkeyz was born. Starting out, I 3D printed gun grips, and soon moved into knife handles. As I have 8 brothers, only one younger than me, you could say I would get the hand me down knives, and boy did we have a lot of them. I never had really nice knives, so I didn’t know about this world of high end knives. As I learned about the idea of customizing knives, and the every day carry world, I fell in love.
In 2022, I was blessed with the opportunity to purchase the machine shop I had worked in for around 10 years with a goal to start manufacturing our own products. United Precision Machining has been growing steady now with more products for Kave Monkeyz along with many other industries. As we grow, I try my hardest to remember nothing is possible without our customers and our team here at UPM and Kave Monkeyz. And also to grow as a team holding our core values high, keeping our customers in mind giving them the best bang for their buck!
Thank you to all of our customers who have believed in and support us as we are always growing and learning.

I love flying, the ocean, and skiing. I started working for Kave Monkeyz January of 2024. Learning about 3D printing and working with knife scales has been a blast! Getting to know what options are available, and what we can create with our imagination, is really cool! Also, seeing these knives transform into a product that pleases our customers and giving them a great experience is rewarding:)
