Review on Enhanced Black Snap-Off Heavy-Duty Blade by OLFA for UltraSharp Results by Morgan Gilmore

I bought these very sharp black blades to replace the ones worn in my Olfa Ratchet Lock Heavy Duty utility knife. This knife was the first Olfa product I have ever bought and the value for money blew me away exactly where I like it. This knife makes the regular stationery knives that everyone uses look pretty bad. It's like comparing a gunpowder rifle to an M16, or a Ford Model T to a new Mercedes. Technology is advancing and smart companies are developing better alternatives. These blades are around 25% sharper than Olfa's silver blades, which makes a huge difference when you're cutting through multiple boxes for recycling. So make a "big" investment of about $16 and buy an Olfa Heavy Duty Lock heavy duty utility knife with a box of these ultra-sharp blades. You will not regret it.
