Technical question - base bevel
What good does base bevel do?
Many times I read on manufacturers HP that the optimal tuning is 2-3 degrees on the side and 1 degree bevel on the base.
The side bevel I understand, I myself tune it to 2 degrees on the sides. I think it works.
But what is the merit in having a 1 degree bevel on the base?
Please, do not come with the 'it helps you not to catch an edge accidentally' explanation.....
Thanks
Ps.: I know this has been discussed a couple of time back in time, but I did not understand it then either. Maybe now someone can enlighten me.

A question for you: what a watch is used for?István wrote:Please, do not come with the 'it helps you not to catch an edge accidentally' explanation.....

Which is the risk of riding "switch" with an alpine board if it has not a tail that comes enough up from the snow? The more the tail is up, the less is the risk to dig into irregular snow.
The same for the edge bevel.
What's strange in this?
Ciao!

another easy answer
When the edge is kept zero on the base, its nearly impossible to polish or maintain perfect because u cannot grind it, sharpen it. Having 1° is making it possible to matain

Theoritacally with smallest bevel angle( 0 degrees) you will get sharpest edge angle.
But yes, you are also right that with very small bevel angle (0.5-1 degrees) one can make it so shine and sharp from bottom side, that end result can be better than having no angle at all.
So things are not always so black and white

I think it is exactly the opposite. Or... at least, the same.Freecarver wrote:I think with base bevel you achieve better acute angle to your edges resulting of making them sharper, useful for icy conditions.
I mean: if you've got 1° of bevel, if you want to have an 88° edge angle you have to use 87° on side edge.
If you have 0° bevel, the 88° are effective even if you ise 88° on the side edge.
I can't realize why a bevel should make you have sharper edges...

Well, I see I've managed to divide the community with a simple question...
I really liked the response of Nils, although I am not sure if it's correct... Why could not one grind the base and keep a zero bevel at the same time?
As for the 'not to cath an edge accidentaly' solution, I have ruled it out because I think when it comes to buying / riding decent carving equipment, I do not think that catching an edge accidentaly is a realistic event.... how many of you have a serious issue with falling due to unwanted catch of an edge? I guess none...

How the hell do you want to hand grind a zero degree edge without touching the base... they are at same height! It means when you grind the steel, it does touch the Ptex.... when you have 1° edge base side, you can polish/sharpen it without touching too much the plastic
Got it?

Tomy eyes the community isn't divided on this question... You've got different reasons, not uncompatible the one with the others...István wrote:Well, I see I've managed to divide the community with a simple question...

The fact that you don't fall doesn't mean that your performances aren't worse.István wrote:As for the 'not to cath an edge accidentaly' solution, I have ruled it out because I think when it comes to buying / riding decent carving equipment, I do not think that catching an edge accidentaly is a realistic event.... how many of you have a serious issue with falling due to unwanted catch of an edge?

It's the same if you say "go on piste with a jeep is the same as if you go on piste with a ferrari: if you are clever enough, you don't crash on a wall!".
Yes, it's true, but the performance are a little bit different..
