Torus vs. Wuertz TW-90: An Honest Comparison
The TW-90 ($3,900-4,150 complete, 2-4+ week lead) is the refinement pick: billet-machined everything, the unique SGA-1 surface grinder attachment, and pro prestige. A Torus Nova/Nebula setup delivers the same working feature set - 90-degree tilt, ratchet tension, dual-axis tracking, variable speed - for $2,245-2,345, shipping now. Professionals amortize the TW-90; shop-builders keep the $1,600+. (Disclosure: this is Torus CNC's site; Wuertz data verified July 2026.)
Disclosure: we’re Torus CNC — one side of this comparison is ours. TW-90 specs and prices below come from Wuertz Machine Works’ own listings, verified July 2026 and linked in Sources. And credit where due up front: the TW-90 is one of the most beloved machines in knifemaking — Travis Wuertz’s grinder shows up in more professional shops (and more YouTube backgrounds) than nearly anything else. This comparison is really about what refinement costs, and when it’s worth it.
The Short Version
The TW-90 is the refinement pick; Torus is the same working feature set for roughly 57% of the price. A TW-90 runs $3,900–4,150 as a complete package — 2HP variable-speed motor and VFD included, 90° vertical-to-horizontal tilt, CNC-machined billet aluminum wheels — on a 2–4 week (sometimes longer) made-to-order lead. A complete Torus Nova or Nebula with our motor/VFD combo lands at $2,245–2,345, assembled and tested, shipping now.
Spec by Spec
| Wuertz TW-90 | Torus Nova / Nebula | |
|---|---|---|
| Complete setup (July 2026) | $3,900–4,150 (2HP VS motor + VFD included) | $2,245–2,345 (chassis + $850 2HP-class combo) |
| Tilt | 90° vertical ↔ horizontal | 90° vertical ↔ horizontal |
| Wheels | CNC billet 6061, dual bearings; 8″ contact wheel standard | Machined aluminum, dual-bearing; billet-machined dual-axis tracking mechanism and tracking handle |
| Tracking / tension | Refined tracking; lever tension | Dual-axis tracking; stainless ratchet tension |
| Availability | Made to order, 2–4+ week lead | Built, tested, ships |
| Notable ecosystem | SGA-1 surface-grinding attachment (a kitchen-maker favorite) | Standard 1.5″ arms — industry attachments fit |
Where the TW-90 Genuinely Wins
- Fit and finish. The CNC-billet wheels and the machine’s overall fit-and-finish reputation are real and earned — a TW-90 feels like lab equipment.
- The surface-grinder attachment. Wuertz’s SGA-1 converts the machine for precision flat work — a genuinely unique capability kitchen-knife makers rave about (and exactly the thin-blade flattening our kitchen geometry guide demands).
- Prestige and resale. TW-90s hold value like few tools anywhere — partly scarcity, mostly deserved reputation.
Where Torus Wins
- ~$1,600–1,900 stays in your shop. Same 90° tilt, ratcheting tension, dual-axis tracking, variable speed — and the difference funds a heat-treat kiln with money left for steel.
- No wait. Made-to-order excellence is still a queue; ours is on the truck.
- Fit and finish, verified by buyers. Torus machines hold 5.0-star averages on both Google (16 reviews) and Etsy (33 reviews) as of July 2026 — “this grinder is legit. Every piece is machined so well,” “beautiful machine,” “even the packaging is professionally done.” Every machine is assembled, test-run, and inspected by hands before it ships.
- Billet machining isn’t a $4,000 exclusive. Our dual-axis tracking mechanism and tracking handle are machined billet aluminum — the parts your hands adjust every session get the machined treatment at this price too.
- Open 1.5″ arms — the broader market’s attachments fit, today and in ten years.
The Fair Verdict
Buy the TW-90 if the grinder is your profession’s daily instrument — the refinement amortizes over thousands of blades, the SGA-1 may be worth the ticket alone for kitchen work, and you will never once regret it. Buy Torus if you want the same working capabilities — tilt, tracking, tension, speed — while your money is still building a whole shop. Both are honest purchases; they’re just aimed at different years of your knifemaking life. Context: the full field comparison and buyer’s guide.
