Better than expected
Near mint condition and a super bargain from amazon warehouse 👍 far far better than expected !!!!!

improved quality and price
Getting to like it more over time. Previous stones blistered and shed their nickel matix in places leaving holes which led to blades catching and ripping even more out. So far this seems to be an improvement. Price is certainly more competitive than prevously.
