Review on X-Acto Z Replacement Blade (100 Count) - Superior Gold Blades for Precision Cutting by Tara Ford

I must have received a box of bad blades. The tips are not sharp at all (leave a torn edge). I only opened the packaging 3 months later and now it's too late to return it. I've used X-Acto Blades throughout my career as a graphic artist before computers, when we used them to "glue" all of our artboards. The X-Acto knife is like a pen or pencil to me. I also bought an X-Acto knife (Z Series #1 Precision Knife - https://www.amazon.com/dp/B00IR9FH90/ref=cm_cr_ryp_prd_ttl_sol_1) and it doesn't look like they use it either. The handle is not tight the blades fall out easily after a few cuts. Disappointed with both of these products.
