 Poster: A snowHead

My current ski is 1:1
If I want to put on a 2 segree edge, what guide am I supposed to buy - is it an 88 guide?
Do I buy a 90 degree guide to maintain the base or an 89?
COnfused...

Because your edges are 1,1; that's 90 degrees - it's square, so the 1 degree at the side is offset by the 1 degree on the base to make 90 degrees.
So 2,1 is 89, and 3,1 is 88

@dp, Nope. The base bevel doesn't extend all the way across the base so the guide needs to match just the side angle.
@GordonFreeman, Get an 88 guide.

@GordonFreeman, for the base edge I use a specific base edge guide which was a cheap plastic file guide which measures from the base so is for me (and for you) 1 deg. One of my multi angle edge guides also has a base edge guide built in, might be worth checking.
For a side angle of two then it’s an 88 you need, with a 1 base angle the actual edge will be 89 but in terms of file guides it’s not relevant.
Be careful with the base edge as it’s only possible to file it to the same angle, or sharper, this means if you overdo it then the only way to go back to a flatter angle is with a base grind. I don’t know why unless you’re a racer you would need to go more than 1 deg on the base. Personally I find accurately doing the base edge more of a challenge than the side edge.

Out of interest, what use is a 90 side edge sharpener then? That means flat?
Kuu sell them. Kuu ice buster

@GordonFreeman, I don't know about skis, but some snowboards (well, mine at least) use a 90 degree edge.
Edit: in ski speak would that be 0:0?

@GordonFreeman, some useful information.
https://the-raceplace.com/pages/how-to-tune-edges
I’m not sure what your question means, however some skis have a 0 base angle and 0 side angle for which a 90 guide is the one to use.
I’ve experimented with various angles over the years and unless it’s icy it’s hard to tell the difference, the main thing with edges is never to let them get dull, rather than get too concerned with edge combinations. With new skis I’d say leave well alone.

No, no & no!
The correct notation for stating edge angles is NOT to refer to the angle subtended - the subtended angle should never be quoted as it just confuses folk!
Both the base edge and the side edges are quoted seperately and the base edge angle is always stated first.
The actual base edge angle is measured from the horizontal plane and the vast majority of skis have a 1 degree base edge angle.
The actual side edge angle is measured either from the vertical or the horizontal plane. So a 1 degree side = an 89 degree & a 2 = an 88 & a 3 = an 87.
So for a Dynastar ski with a 1 degree base & a 1 (=89) side edge the correct notation is either a 1,1 or a 1,89. And to tune this ski you'd need a 1 or an 89 degree side edge angle guide.
So for a K2 ski with a 1 degree base & a 2 (=88 ) side edge the correct notation is either a 1,2 or a 1,88. And to tune this ski you'd need a 2 or an 88 degree side edge angle guide.
So for a Blizzard ski with a 1 degree base & a 3 (=87) side edge the correct notation is either a 1,3 or a 1,87. And to tune this ski you'd need a 1 or an 87 degree side edge angle guide.
Here's a few diagrams that might help: https://www.thepisteoffice.com/index.php/1-tuning-advice/terminology.html
And there's a list of manufacturers angles here: https://www.thepisteoffice.com/index.php/edge-angles-wax-data/15-ski-manufacturers-edge-angle-specifications.html. Note that some manufacturers still don't quote their specs correctly and most of their staff/distributors don't have a clue and their websites are often incorrect!
And no ski shipped to the great unwashed is shipped 0,0 as it'd be unskiable without any base edge angle. The only skis that might leave a factory with those angles would be for high-end racers to allow them or their tech to set their own preferred angles, especially on the base edge.
A 0/90 degree side edge angle guide is a legacy from the old straight ski days and should NOT be used on a modern shaped ski!

I got told by a guy at stockli that the skis I was looking at come with a factory tune of 1 degree base and 2 degrees side. I then asked if that meant I needed an 88 degree side edge file guide. He said no you need an 89 degree edge file guide. I'm confused.

@Powder Pete, I draw on the side edge with a black felt tip pen. When you start to sharpen the file will remove the pen mark evenly across the edge if you are filing accurately with the same side angle. If the bottom or the top of the edge is being removed first the you’re either lessening or increasing the side angle respectively.

@Powder Pete, you Stockli guy is clueless - as are many factory/shop folk.
Your Stockli guy is correct in that their non-race skis come 1,2 (=1,88 ) but that means you'll need a 2 degree or 88 degree side edge angle guide.
As stated above, the subtended angle is never used/referred to.

You know it makes sense.

Ah so I was right. You just minus whatever degree they say from 90 degrees. Cool

No doubt it depends on the type of snowboard. For my slalom boards the factory angles are 0.5 base and 3 side. Of course many snowboarders never use the edges anyway 
My own file guides all seem to have essentially preset standard angles on them so it's fairly hard to get it wrong, so long as you know what a right angle is.

The last time I had skis serviced by someone other than me (in VT) they came back 0/90. It made for an interesting days skiing until I worked out what was wrong When I had a word with the shop their reply was that the edges would stand up to grinding rails better! I don't think I've ever been grinding rails though I did once have to jump over one which I hadn't spotted taking a shortcut in low vis. I suppose it makes a kind of sense, a blunt edge goes blunter slower than a sharp edge.

An edge at 0deg ie flat with the base will catch quicker than a bevelled edge regardless of the side angle..

Fortunately I was already very good at falling, however it took me a while to work out why I seemed to be practicing it more than usual.
