2-PACK – X-ACTO Z Series Light-Weight Replacement Blade, No 11, 4-7/8 in L, Stainless Steel Blade, Gold Hue, 5 blades per pack

If your not familiar with standard blades, these may not be a big deal. However, if you regularly use standard blades, you will definitely tell the difference with the z series. Its not dramatic, but noticeable. If your a perfectionist with perfect sharp cuts, then you know that after 2-3 cuts a regular blade goes to the utility pile. With the z series you can get 5-6 cuts before I would say it goes to the utility pile. If your saying to yourself, “This guy is crazy. Who only uses a blade 2-3 times!?”, then just stick to standard blades. You will never tell the difference. If you get were im coming from, then get the z series, they are worth it.
