Good quality ski edge guide! Nice anodized finish with chamfered edges. It won't damage your base and it should hold up for a decently long time. It is a little on the smaller side, but that doesn't affect the functionality at all. Shipping was quick to Canada, about 3 weeks. I would recommend, the local shop sells this for $40-50 CAD ($30-40 USD).
i think the edge knife is not enough for edge tuning.
