I don't think the Ascentionist is still made? Current equivalent would be the Knifeblade.
Anyway, I have an Ascentionist. I like it a lot but I don't think it would be suitable for your purposes. I find it great for winter alpine walking, snowboarding etc. when it's well below freezing and definitely no chance of rain or sleet.
It would be rather too heavy for summer in the Alps, and I think for Scottish winter I'd want something more waterproof.
