Inspired by the familiar comfort of a bygone era’s optimism, Memento Tenax offers a quieter, more enduring truth—tenacity is not always graceful, nor is it without cost. On one side, a lone skeletal familiar clings to a weathered limb, a stark emblem of survival against time itself. On the reverse, an ornate banner bears a simple command: Hang in there, baby.

Rendered in a style reminiscent of medieval engravings and antique keepsakes, this piece balances solemnity with a touch of dark humor—an heirloom for those who understand that perseverance is, above all, an act of will.

A series inspired by Musashi's Book of Five Rings

from the Book of Water:

“If you do not look at things on a large scale, it will be difficult to master strategy.”

This speaks to the importance of perspective — not just in combat, but in life, craft, and business. Musashi reminds us that seeing only the immediate or the small picture limits our understanding. Mastery comes from stepping back, seeing the patterns, and thinking beyond the moment. It's about developing the vision to anticipate, adapt, and respond with clarity.

from the Book of Earth:

" From one thing, know ten thousand things." is a distilled interpretation of a central idea from The Book of Five Rings (Go Rin no Sho), specifically from the “Earth Book” (地の巻, Chi no Maki), which is the first and foundational scroll.

In that section, Musashi lays out the principle that mastery in one domain (such as swordsmanship) can teach you the universal truths that apply to all arts and strategies.

from the Book of Fire:

"When you attack, do so with a full and unhesitating spirit."

In the Fire Scroll, Musashi teaches that true strategy demands not only skill, but total commitment. This quote is a call to act with boldness — to strike with clarity, decisiveness, and conviction. In combat, hesitation breeds defeat; in life, it dulls the edge of purpose. Whether wielding a sword or making a choice, the principle remains: once the moment to act arrives, there must be no doubt, no delay — only presence and power. Fire moves forward. So must you.

from the Book of Wind:

"Fixation is the way to death. Fluidity is the way to life." — Book of Wind

In the Wind Scroll, Musashi warns against rigidity, whether in combat, thought, or daily life. To cling too tightly to form, style, or expectation is to stagnate. Like air and clouds, the warrior must move freely, adapting to the shifting rhythm of the world. This teaching is not only about survival in battle, but about vitality in living — to flow rather than to cling, to breathe rather than to choke. Life belongs to those who remain fluid.

It's that time of year!!! Almost...trying to get a head start.

Every top is a One of a Kind!

I'm doing this a little different this year and going forward. I'm limiting the amount available and "sculpting" each top. I love to think of these as little treasures that you're buying for yourself or a loved one that will carry through the years. For that reason, I want to spend a good amount of time on each and so limiting the number available and sizes.

Each top is machined, filed, sanded and shaped to perfection (as perfect as I can get by hand anyway). It's then finished and sealed with a metal oil.

Machined by hand from solid metals and material varieties.

Tops shown are NOT what you will be receiving...just giving you an idea.

Limited to 100 this year!

You may purchase as many as you like until sold out for the season.

The Mystic Seer will guide the way!

"Worrying is like paying a debt you don't owe"

Our Worry Coin is minted from solid metal in the U. S.

Available in Bronze, Copper, blackened Iron & .999 Silver.

Mokume version is limited and will vary in patter from coin to coin.

Blackened Iron version does not have reeding (little lines) on the edge. Iron is too hard to make this happen but we think it works without in this case.

Approximately 1.25" diameter

Solid Silver option is 1 troy ounce.

The most remarkable thing about this favorite quote of mine is the simplicity and truth behind it. We worry almost constantly and there's nothing in this world saying that we have to. It doesn't change anything or fix the problem, but we do it anyway. We constantly pull from our bank of emotions and hormones to pay for this debt that doesn't exist.

A few years ago, I started manually machining various types of Worry Coins. They vary in metals, woods and sizes. Last year I had the idea that I'd laser engrave this quote into a coin but it was missing something and made these hand made coins even more expensive. I really wanted to be able to offer a more affordable version of a Worry Coin with this quote but, at the time, was not aware of Shire Post Mint's ability to create a concave surface on one side, so I shelved the project. A few months later, I saw what they could do with a coin so reached out to my favorite designer, Mike Major, and got to work. I couldn't be happier with the result. The size, weight, design and cost are the perfect balance and I'm sure you will enjoy.

Just a simple "worry coin", no frills, no spinning...just feels comforting in the hand.  These are manually machined in limited quantities.

One of a kind. You will receive the coin pictured.

Intended as a worry coin

In Japanese mythology, the oni are powerful supernatural beings often depicted as horned ogres or demons, embodiments of both malevolence and divine justice. Originating from ancient folklore and Buddhist traditions, oni were once thought to be humans transformed by overwhelming anger, jealousy, or wickedness, condemned to guard the gates of hell or punish the corrupt. Despite their fearsome appearance — bulging eyes, sharp fangs, and fierce expressions — oni also carry an element of protection, warding off evil and misfortune. This dual nature makes the oni a timeless symbol of the balance between destruction and protection, embodying the darker energies that must be confronted to preserve harmony.

My dad used to make small runs of bottle openers. His mantra was 12-15. Any quantity higher than that and it gets repetitive and boring. I agree but fear of being able to come up with new designs always urges me to make larger editions. Well...I'm going to try it the way my pops did. Here's the first attempt.

Cast by hand in Sterling Silver

Limited Edition | 13 Sterling Silver 

For thousands of years, the eye has stood as one of humanity's oldest symbols—of awareness, intuition, and the pursuit of truth beyond what is immediately seen. Across cultures, it has represented vigilance, wisdom, protection, and the quiet reminder to look inward before looking outward.

At its center rests a Ruby, forming the pupil of the all-seeing eye. Long associated with clarity, vitality, and conviction, the ruby serves as the focal point of the piece, drawing the eye while inviting a moment of stillness.

Designed with a smooth, concave reverse, Oracle is more than a coin—it's a worry stone meant to be carried, held, and returned to throughout the day.

Specifications:

App. 1.7 ounces (1.5ish Troy Ounce)

8mm lab grown Ruby

1.25" diameter

Lo, mark the worm that turneth on itself, whose hungry mouth devoureth its own tail. In this round lies the endless wheel of being, where birth is but death in other guise, and ruin but the seed of fresh creation. All things do circle thus, and thus all things are one.

The Ouroboros is one of the world’s oldest and most enduring symbols, first appearing in ancient Egypt over 3,000 years ago and later woven into Greek philosophy, Norse myth, and the practice of alchemy. Depicted as a serpent consuming its own tail, it represents the eternal cycle of life, death, and renewal. Its circular form embodies infinity and the unity of beginnings and endings, reminding us that nothing is ever truly lost — only transformed.
