90 degrees ... 87 degrees edges ? what are your experiences

Postby e-mammut » Tuesday 20 April 2004, 12:39

I sharpen my edges since several years and love riding when the
edges are razorsharp- I am using 87 degrees from flat bottom
to edges (on my K2 Eldorado 174). Since I tried a Swoard 175m ,
i am wondering what will happen to the carving-behavior of a
swoard board at differently angled edged of same sharpness.

-do boards tend to be too agressive
-do edges wear out too fast
at 87 degrees compared to 90?

-why does the swoard developers suggest 90 degrees?

Hi Mammut,

Hi and welcome to the forum!!!

Sorry, I really don't want to be rude. But as there are some issues discussed several times, I would like to introduce you into the search function :arrow: . When I type angle & edge in the field, it gives me the following results:

This may already help you, if not: Don't be shy, to ask a lot of further questions ;) ;) ;)

Have fun here!!!

Edge

Postby István » Tuesday 20 April 2004, 16:21

As for myself, I prefer 88. It gives me more edgegrip. On the other hand, the smaller the angle, the bigger the damage a stone can do.

Some go for 89 on the side of the edge and -1 on the bottom. I've never tried but does not sound too good for me.

István

ps.: Swoard guys have also changed to 88, but have not changed the text on the site.

yes depends on who

i've switched to 87 on the side, 1 on the base: total angle 88 now. I find it a bit more efficient, and it doesn't wear out as fast as i would thought it would... !

cannot remember if J and P did it too!

Nils,

It is 86 altogether, isn't it. Never heard of anyone riding 86 degree edges.... of course that does not mean too much..... two years ago I'd never heard of anyone carving on 22cm wide boards :-)

measurement

Hi Istvan,

obviously it's not that easy to communicate the angles of edges, especially as cveryone here uses them in a different way. If I got Nils right, he has 88 between the two sides of the edges, 87 between base and edge outside an 181 between base and edge downside

A little bit confusing ;))

I don't have any vodoo in my edges, just flat with 90°, my board works anyway. Does anybody know, why?? :roll: :wink:

Edge angle

A little drawing is better to understand

Is that right Nils ?

this is correct

Postby nils » Wednesday 21 April 2004, 9:51

87+1=88 :)

it took me a while also to understand it!

other examples:
side: 88
base: 0.5
total : 88.5 edge angle

side: 87
base: 1.5
total= 88.5 same edge angle, but less grip, faster ( theorically ) base..

This is why you need good tools to make good precise sharpening!
