Do you detune? Why or why not?

[XXX-er]

I never go to shops for a ski tune

do they detune after a base grind ?

my base grind seemed to work great right out of the m/c and since they couldn't remember to load the skis on 2 trys I doubt they detuned them

Detune is also a band in the Maldives you know mon

Amusing that whether softening the edge beyond the contact point counts as detuning or not is pedantic, and needs to get out of the way of the real discussion in re: gummi stones.

I get that it’s a style/technique/preference thing. But can we get any more precise about that? A possible corollary: long skis don’t bother me, and I prefer them. Detuning and ski length isn’t meant to be a value judgment, but it does seem indicative of…something….beyond just personal preference.

I just sharpen through the contact point and not the end of the tips and tails. Natural detune I guess. I think Djongo's point about how you ski and weight matters too.

But I have a bit of a laziness about this to be honest. Who was the golfer (Hogan maybe?) who said spend the first few holes trying to fix your swing, then spend the rest of the 18 playing whatever swing you brought that day? That's kind of how I ski. Pick a ski, get out on the snow, see what's happening between the two for a run or two, then just ski in a way that works. Hard snow with some windblown scraped ice with ON3P Jeffreys with worn edges is different than Optic Blades with a full sharp edge on softish hardpack is different than detuned Deathwishes on 4" of fresh cover. And I'm perfectly happy on all of those. On the first one I'm stomping each turn through the heel and ball of my foot and trying to turn on about 18" of ski, on the second I'm float carving and dancing, on the last I'm gentle through the apex and bouncing up out of the turn. And all of those are fun.

I can feel a hooky ski, I just don't really mind it all that much for some reason.

Deburring is the word you're looking for.
A detune is exactly as uni stated

31 seconds into that Sidecut video: “pull your Gummi out and detune as necessary”.

Deburring is getting rid of the hanging burr created from sharpening. I’m not talking that, I’m talking about intentionally taking sharpness out of the edge.

Now that we have that cleared up, the Swix video clearly shows detuning of the effective edge of the ski with a gummi, and that does change the way a ski feels and performs.

If you can’t feel it maybe it’s because of the ski, the conditions, or your skill/technique.

I can totally tell if there’s a burr or the edge is really sharp

I detune the tip and tail parts that don’t contact the snow. I have a soft stone (a little firmer that a gummy, it definitely knocks the edge down) that I carry in my pocket that I’ll use to fine tune a ski the first few days.

I like to have an edge on firm snow but I don’t like a ski edge that feel’s totally locked in or grabby.

For me in various brands:

HL skis don’t tend to need any adjustment as MO does an awesome job hand finishing.

Praxis need an aggressive detune normally.

Race room Dynastars (made in France) need an aggressive detune. Had a pair of LP105 so sharp you could hear the edges grip the snow. They were scary as fuck until I redid the edge bevel and detuned. But other race room skis I’ve gotten from them are also overly sharp.

Made in Spain Dynastar’s/Rossi are generally really dialed for my liking and I just do a quick deburr but am not afraid to ski straight out of the plastic. The MF112 I just got I haven’t touched the edges at all and they feel great.

ON3P need a mill file.

Blizzard are pretty good out of the box, maybe a quick detune in tips and tails and then ski them.

I use a stone to dull the edges a little on soft snow skis, detune if you will

as necessary could also mean not at all

which does not require stones or gummis or emery cloth

so there is nothing to buy or lose

does intentionally doing nothing for 40 yrs still count as " detuning as necessay " ?

That wasn’t intended as a you ‘you’, but a royal ‘you’.

Yeah, so? That's pretty much what I said. That's part of a detune. The extent of which depends on user

You said the word I was looking for was deburring. I was not. I was clearly talking about detuning as it is described following the highlighted word ‘detune’ in the Swix manual.

Jesus dude. You stated running it through the effective edge zone, not down into it. From the ends. That is a detune

Wow, this thread really hit the fan!

Not stepping in to the minefield about splitting hairs of what "detuning" really means, but I for one (on freeride skis that encounter soft snow mostly) enjoy dull edges outboard of widest sections, i.e. the tapered parts of tip and tail that never really engages firm snow. Especially if the extremities are on the soft side. Soft tips in compact but soft snow with sharp edges will make skis twitchy. Guess that's the reason why certain manufacturers applies hull tips...

Stiffer tips don't need as much rounding of edges that soft tips need.

Stiff tips also drive extremely well when submerged in pow, where they also contribute to great floatation... But I think that's enough for a thread of its own. As many peeps on here seem to think they're experience tip dive, and are afraid of going over the bars if they can't see the tips six inches above the snow surface... Again, think I need to start a new thread about that...

[XXX-er]

well by definaition tuning would be sharpening the ski and then using the gummi or whatever one uses on their edges

while detunning would be leaving them sharp tip to tail ?

I'm ok with white back ground

for the blue i just hi-lite to read the text

[half-fast]

I don’t detune anything. If the edge isn’t hitting firm snow why? I have a pair of praxis protest and powder boards and haven’t detuned them and they are great deeper snow

Because sharp edges will affect the skis behavior in soft snow as well. But if yer happy, stay happy!

[half-fast]

I’m happy. I don’t believe it will make a noticeable difference.

Yeah, I once made love to a woman wearing a condom. It was absolutely great!

Then I was fortunate to do the same without ..

After that, there was no way back.

Dull edges on tapered tips and tail might lead you to new experiences. Red pill anyone?
