There's some numbers online that say there is a ~0.25575% chance of getting a knife after opening one case. I'm not sure how many cases you opened, but I'll just do the quick easy math for 3 cases. Since we want the probability of the same event happening 3 times, we want to multiply the percent chances together three times: 0.25575 * 0.25575 * 0.25575. Plugging that into a calculator, I got a hella low% chance of unboxing 3 knives in a row. Chances will be slightly higher if you opened more then 3 crates, which I'm guessing you did but still. Nice.
(0.016728111984375 percent chance- about 1 hundredth of a percent or just hella not going to happen. Feel free to check my math, not feeling my best right now so I probably messed up in those exactly 3 numbers)
