The Blue Blade in 60 seconds

Read the transcript

Your blades get swapped and shipped to the sharpener every week.

Carbon and tool steel rust in wet environments, eating away at the edge life.

Every blade swap takes up your time, and increases your sharpening bill.

It's like having a great car, but terrible tires that go bald frequently.

Meet the Blue Blade.

Rinks report 6 to 8 weeks between sharpenings, or at least three to four times longer.

And less than half the weight.

In our cost model, 208 sharpening trips fall to just 52 over two years.

This means thousands of dollars saved, per machine.

The Blue Blade has a stainless steel edge that resists rust.

It's heat treated carefully, in a process similar to aircraft parts.

And precision ground, to cut ice smoothly.

It drops right into your existing machine, and your service routine, with your same sharpening house.

The only thing that changes is your bill, and your time.

Rinks from Alaska to Florida have already bought the Blue Blade.

It teaches metallurgy that is true of any steel blade. It is not a depiction of how we make ours.

0:00The finished blade standing on end, with a cross-section of its edge beside it. Where the film is going.
0:02The recipe. Iron atoms in a lattice, chromium taking an iron's place, carbon squeezing into the gaps.
0:04A plain grey bar of steel standing on end, with the blade it will become drawn over it as a construction line.
0:06The ceiling. Three gauges rise and each stops dead against a limit the alloy set.
0:08The heat. The bar held hot in a chamber until its crystal structure changes.
0:10The quench. The hot bar plunged straight down into the bath: cooled fast, carbon trapped in place. Hard, and brittle.
0:11Locked in. The lattice strained out of square, the carbon unable to get out, one bond snapped.
0:14The second heat. A gentler fire trades a little hardness back for toughness, and the balance levels.
0:16What the heat leaves. Grains refine from coarse to fine and a crack stops dead against a boundary.
0:18The grind. A wheel runs down the edge and lays the bright bevel behind it.
0:20Dead straight. A waved edge cuts ripples into ice; a true edge does not.
0:22One angle. The blunt tip grinds away to a true point, held at one consistent angle.
0:23The mark. The blade is blue for the first time since the opening, and the mark is cut into it.
0:25The cut, seen from above. Rough ice ahead of the blade, a clean striated swath behind it.
0:28The blade in blueprint, the whole film in a column of four glyphs beside it, the wordmark, and back to frame 0.
