I had previously considered the razor mild as is the general opinion on this forum.It is a beautifully made stainless steel razor.I bought it along with the stand made for the razor.I have used it with shims and without shims.I have used it with any number of blades until today.Enter the Kai.What a huge difference this blade made in the performance of the razor.A marriage made in heaven! I toyed with the idea of putting the razor and stand for sale on BS&T until todays three pass bbs shave.A keeper imo.The weird thing is the blades did not seem to vastly improve the performance of the other razors I tried it in.As always ymmv.
