Built by a scroller.
For scrollers.

I’m not a programmer. I’m a project manager who fell in love with a scroll saw, got frustrated with the tools that didn’t understand the craft, and decided to build the one that did.

A Ryobi in a box.
Still in the box.

While on disability in retirement, a friend decided I needed something to do. One day she dropped off a Ryobi 16″ scroll saw — still in the box. I had no idea what was about to happen.

Two weeks later, after watching almost every Steve Good video on YouTube, I finally got on the saw.

“I fell in love.” The focus. The quiet.
The way everything else just… fades.

Every board is
a calculation.

Here’s the thing about being on disability: supplies cost money. Mistakes cost more. I wanted to design my own patterns, but the tools out there? Either way out of my budget, or built for graphic designers who’ve never held a blade.

They don’t understand kerf. They can’t warn you when an island’s about to fall out. They think in pixels, not blade width.

So I had a choice: walk away from scrolling, or build what we were all missing.

I chose to build.

No guessing.
No AI improving your design.

RipSaw is a pattern maker built specifically for scroll saw, fretwork, intarsia, and segmentation artists. You own every line. What the software understands:

Kerf

Your blade has width. RipSaw makes that the foundation of every calculation — entered once, never forgotten.

Islands and Seams

Scroll saw mode detects floating islands. Intarsia and segmentation workflows focus on piece fit, seam snapping, overlaps, and near gaps.

Bridges and Cut Lines

Bridge placement stays in your hands. RipSaw helps you see where connection matters and gives you cut-line tools that respect the blade.

Pattern Preview and Print Output

Preview the pattern without construction clutter and export at real-world scale when you are ready to take it to the shop.

Intarsia Tools

Wood palette, grain direction arrows, sequential piece numbering. The full intarsia workflow, inside the same design tool.

Shape & Line Tools

Draw, duplicate, flip, curve. Node editing. Everything you need to get what’s in your head onto the pattern — and from there, onto wood.

It kept ripping
my ideas apart.

I’m not a programmer. I’m a project manager. But I know how to break down complex work, and I partnered with AI to help me build this.

Early on, the AI kept busting my chops. Every idea I had, it would tear apart. “That won’t work.” “Here’s why that fails.” Constantly ripping me up.

“You know what?
I’m calling you RipSaw.
Because you rip me up
all the time.”

— The moment the name stuck

RipSaw exists because
they made me stay.

I can’t talk about this journey without talking about the people who got me here.

Her patterns make me dream of scrolling. That’s the only way I can describe it.

Newton Makes

Skills beyond my comprehension. The kind of craftsmanship that makes you want to keep pushing.

Danielle

A wholesome family woman whose heart shines out in her work. You can feel it in everything she creates.

This is for them. And for everyone they’ve inspired.

I still can’t believe I can create the things I create now. Every time I finish a piece, there’s this moment of genuine surprise.

That’s what I want RipSaw to give you. Not just a tool — growth in your craft. The confidence to try patterns you thought were beyond you. The ability to design what’s in your head and actually cut it.

I made that. Damn, I can’t wait to see what you make.
