Looks like a standard Swedish full hollow to me.
The scales, etching & "77" stamp all looks very generic.
Any one of the bigger makers could have made it.
AFAIK there is no forge or maker called "hästsko"
But I have seen a few knives with that logo.
When I come home I can double-check it against some Eskilstuna knives reference books I have.
Best guess is that it's made by someone for some hardware-store or company that used that logo.
It should most probably shave very well.
Made 1940-1950 based on the scales.
Value? maybe 150-200 SEK on a good day
Can-can scratch patterns!
