Blade life: Planning range, not a manufacturer figure and not measured by us: 300-450 linear feet wet on cured concrete, against 150-250 for the Ultra Value on the same basis
✓ Best for
Cutting that mixes concrete, including reinforced, with asphalt, pavers, block or light steel, per VA's stated uses.
✗ Not for
Bare cured concrete on a budget, where the Ultra Value costs less per foot on this site's planning ranges.
Pros
- VA's Premium tier: 'best diamond quality with higher diamond concentration,' in VA's words
- Sold by VA for concrete including reinforced, asphalt, pavers, block and steel up to 5/8 inch
- Laser-welded turbo segments, with drop segments that protect the core from undercutting
- Wet-or-dry rated, fits every major 14-inch cut-off saw with included 20mm bushing
Cons
- Upfront cost is about 2.5 times the Ultra Value, and on bare cured concrete it costs more per foot on this site's planning ranges ($0.46 against $0.35)
- Premium tier — overkill for residential one-off cuts on standard cured concrete
The Virginia Abrasives 14-inch Premium Sparkie is VA’s Premium-tier 14-inch blade, sold as a multi-purpose blade for concrete including reinforced, asphalt, pavers, block and steel up to 5/8 inch. Buy it when the work mixes those materials or runs into rebar. On bare cured concrete the Ultra Value costs less per foot.
Availability
Back in stock on Amazon as of September 22, 2026 at $174.30, with a small quantity showing. This blade has sold out twice since June, so if the listing shows out of stock when you read this, the VA storefront on Amazon is the fallback and the Supreme Pro is the in-stock step up from the Ultra Value.
Who this blade is for
Daily production crews running reinforced concrete cuts on 14-inch handheld cut-off saws or chop saws. Foundation work, slab repairs with #3-#4 rebar contact, parking structure cutting, demolition prep where blade-swap downtime is the operational constraint.
On standard cured concrete with no rebar, the Ultra Value is the better economic choice at any volume. This site’s planning ranges put it at about $0.35 a foot against the Sparkie’s $0.46. The Sparkie’s case is harder material and fewer blade swaps on long jobs, not a lower price per foot.
How it performs vs the Ultra Value
VA positions the difference on diamond quality and range of use. Its tier language gives the Premium line “best diamond quality with higher diamond concentration,” and it sells the Sparkie for concrete including reinforced, asphalt, pavers, block and steel up to 5/8 inch, where the Ultra Value is sold for general-purpose concrete and masonry. We have no measurement of either blade on rebar.
This site’s planning ranges on cured concrete cut wet are 300-450 linear feet for the Sparkie and 150-250 for the Ultra Value. Neither is a manufacturer figure or a measurement of ours. VA’s product pages give the Sparkie 10mm segments and the Ultra Value 12mm. VA’s tier language puts the Sparkie above the Ultra Value on diamond quality and concentration.
| Spec | Sparkie | Ultra Value |
|---|---|---|
| Segment height | 10mm | 12mm |
| Bond | Not published; sold as multi-purpose | Medium |
| Construction | Laser-welded turbo segments | Laser-welded, per its Amazon title |
| Planning life (wet, 4k PSI; not measured, not a VA figure) | 300-450 ft | 150-250 ft |
| Price | $174.30 | $69.99 |
| $/foot (middle of planning range) | $0.46 | $0.35 |
The Ultra Value wins on $/foot on bare cured concrete. We have no rebar figures for either blade, so the Sparkie’s case on rebar rests on VA’s stated uses, and its longer planning range means fewer blade swaps on a long job.
Saw fit
Same arbor profile as the Ultra Value — 1-inch arbor with included 20mm bushing. Fits:
- Stihl TS 420 (20mm spindle, bushing IN)
- Husqvarna K 770 / K 970 (1” or 20mm, either way)
- Milwaukee MX FUEL COS350 (1” or 20mm)
- Hilti DSH 700-X (20mm or 1”)
Max blade RPM is 5,500. Every 14-inch handheld saw runs below that — safe.
Disclosure
Matt Lipman is CEO of Capstone Holdings Corp. (NASDAQ: CAPS) and a board member of Virginia Abrasives. He discloses this relationship on every page that recommends a VA product. The Sparkie is the right blade for a specific use case: work that mixes concrete, including reinforced, with other materials, where one blade saves a swap. When you’re cutting occasionally and the Ultra Value would be the better choice, we say so on the VA 14-Inch Ultra Value product page.

Frequently Asked Questions
Does the Sparkie fit my saw? ▼
Yes if it's a 14-inch cut-off saw — Stihl TS 420, Husqvarna K 770 / K 970, Milwaukee MX FUEL COS350, or Hilti DSH 700-X. The 1-inch arbor with included 20mm bushing fits all of them.
How is the Sparkie different from the Ultra Value? ▼
VA sells the Sparkie as its Premium-tier multi-purpose blade, for concrete including reinforced, asphalt, pavers, block and steel up to 5/8 inch, with laser-welded turbo segments; the Ultra Value is VA's general-purpose 'better' tier for concrete and masonry. VA's product pages give the Sparkie 10mm segments and the Ultra Value 12mm. How much longer it lasts is not published by VA and has not been measured by us; this site carries planning ranges of 300-450 linear feet for the Sparkie and 150-250 for the Ultra Value on cured concrete, cut wet, and labels them as planning ranges.
What's the per-cut cost vs the Ultra Value? ▼
Run our cost-per-cut calculator with both blade prices. At the middle of this site's planning ranges, $174.30 over 375 feet is about $0.46 a foot for the Sparkie, and $69.99 over 200 feet is about $0.35 for the Ultra Value. On bare concrete the Ultra Value wins per foot; the Sparkie's case is rebar and mixed materials, which VA lists among its uses.
Wet or dry cutting on the Sparkie? ▼
Both rated. On concrete, OSHA Table 1 lists water fed to the blade as the only control for handheld and walk-behind saws, so cut wet on any crew job. The Sparkie's laser-welded segments are rated for wet and dry use.
How long does the Sparkie last on rebar? ▼
We have no rebar figure for the Sparkie. As a planning estimate, not a measurement, take 30 to 50 percent off the 300-450 feet this site plans for bare concrete, which gives roughly 150-315 linear feet wet. VA lists concrete including reinforced among the Sparkie's uses. For heavier #6+ bar, step to a dedicated combo blade; see our guide to cutting rebar with a diamond blade.
