粗面2000，精面5000的家用磨刀石不常见

[@DAVIDMILLER-nc9vo]

I believe the commentator means PARALLEL and PERPENDICULAR, not vertical and horizontal. Vertical and horizontal are relative to an objects position on the earth. Parallel and perpendicular are the relativity of two objects to each other..

除以10就是这块磨刀石真实目数了

我也這樣覺得 買到騙人的磨刀石

加钢刀你正在用吗 ?

[@user-of8wl4qp5p]

请教一下，刀刃向前的时候，是推出去用力还是拉回来用力？

[@MeiShiQiang]

拉回来的时候更用力

[@geromena980]

@@MeiShiQiang 视频里0:48处不是说前推的时候要重一些，回拉轻一些吗，是视频里说错了吗？
