The hands behind every piece

Hi, I'm the maker behind TensorPrana. I'm in my late thirties, working out of a small workshop in Ninh Bình, Vietnam — a quiet province of limestone mountains and old temples in the north, where bronze and copper have been worked by hand for over a thousand years.

I make energy tools out of pure copper. By hand. One piece at a time.

How I got here

For most of my adult life, I lived in the city. I had what most people would call a dream job — good pay, a clear path, the kind of role you don't walk away from lightly.

But somewhere along the way, I stopped feeling like myself in it.

I'd come home tired in a way that sleep didn't fix. I started reading — about energy, about the body, about the old crafts. I read about Wilhelm Reich, about Slim Spurling's tensor rings, about sacred geometry and the cubit measurements that ancient builders used long before anyone could explain why they worked. I read about copper — the way it carries current, the way every living nervous system runs on something close to the same principle.

I made my first tensor ring on a weekend, just to see if I could. I sat with it. I felt something I couldn't quite name. I made another one.

Six months later, I left the job. I packed up the apartment, came home to Ninh Bình, and set up a workbench.

I was almost forty. People thought I was crazy. Some days I thought I was crazy too.

That was a few years and a few thousand coils ago. I haven't looked back.

What I make

Every piece in this shop is made from 99.9% pure copper, shaped, coiled, and tuned by my own hands:

  • Tensor Rings cut to sacred cubit measurements — 1/2 Cubit, Lost Cubit, Sacred Cubit — and tuned to frequencies like 144 MHz, 177 MHz, and 528 MHz
  • Energy Pyramids built around tensor geometry, often with quartz, triskelion spirals, or sacred symbols at the core
  • Lotus Grids and Flower of Life plates for crystal grid work and altars
  • Acupressure pens, healing wands, and crown pieces for energy work, Reiki, and meditation
  • Twisted strand tools — 2, 3, 4, and 5 strand spirals, each one with its own feel

I keep the copper pure. No lacquer, no coating — I want the metal to breathe and patina the way copper has done for thousands of years. A piece from my bench should look more alive at twelve months old than it did on the day it left.

Why I do it this way

I'm not the only person making tensor tools. But when I started looking at what was on the market, I noticed a lot of it was made fast — on jigs, in volume, by people who don't sit with what they make. The cubit measurements were off. The frequencies were guessed at. The coils were tight in the wrong places.

I came home from the city to slow down. So that's how I work.

I measure twice. I tune by ear and by feel as well as by number. When a piece doesn't feel right, I take it apart and start again. That means I make fewer pieces. It also means each one carries the attention I gave it.

I think this is what I was looking for, back when I couldn't sleep.

For wholesale buyers

If you run a metaphysical shop, yoga studio, healing center, or online store that serves practitioners — Reiki, meditation, energy work, crystal healing — I'd be glad to work with you.

What I can offer:

  • Wholesale pricing on orders from small batches upward
  • Custom orders — your sizes, your symbols, your frequency tuning, your branding
  • Real samples sent ahead of a bulk order, so you can hold the piece before you commit
  • Specs and story behind every piece, so you can pass them on to your customers with confidence
  • Direct contact with me, the maker — no middleman, no reseller markup, no factory floor

I work in small batches. If you need a hundred identical pieces by next week, I'm not the right person. If you want pieces that hold their charge — pieces your customers will feel the moment they pick them up — I'm here.

Get in touch

The easiest way is to send me a message. I answer myself, usually within a day.

If this is your first time picking up a tensor tool — welcome. If you're a practitioner or a shop owner looking for a maker you can trust long-term — even better. Either way, I'm glad you found your way here.

In service,
