Infinity Tools 平面及接合機刀片設定工具（適用於全尺寸平面機；一對）

I've swapped knives on my planer a dozen times the old way, and this jig finally makes the whole process feel foolproof. The pair works together so the blade sits at the exact same height on both sides, which I could never get by feel. Worth every penny if you hate fiddle-fingering with set screws.

The magnetic base holds the knives dead flat while I tighten the bolts, and the whole setup took me about ten minutes for both blades. My cuts have been glassy smooth since I switched over, no more uneven snipe at the ends of boards.

Finally, no more fiddling with feeler gauges for hours. This jig held both knives perfectly while I tightened the screws, and my planer is cutting smoother than it has in months.
