UMP-45 | Blaze

UMP-45 | Blaze is a Mil-Spec Grade SMG skin from the ESL One Katowice 2015 Mirage Souvenir Package. The “Blaze” finish is applied to the UMP-45. No key is required to open this container.

The UMP-45 at $1,200 has the highest armor penetration of any SMG at 65%, making it viable even against armored opponents on force buys. Available to both sides, it bridges the gap between SMGs and rifles on tight budgets.

UMP-45 | Blaze has a float range of 0.00 to 0.08 and is available in 2 wear conditions. In CS2, the float value is permanent — set at drop time and unchangeable. It controls how scratched or clean a skin looks within its wear tier. Extreme floats carry significant premiums: 0.00x copies are prized for their clean look, while 0.999x Battle-Scarred copies like the iconic AWP Asiimov "Blackiimov" are collector's items. Some skins are float-capped and cannot exist in certain wear conditions.

This skin has a Souvenir variant. Souvenir skins drop from souvenir packages earned during Major tournaments and feature gold stickers from the event. They cannot have StatTrak and are generally rarer than standard versions.

As a Mil-Spec Grade item, UMP-45 | Blaze has a 1.0666% chance per opening (1 in 94). Rarity in CS2 directly affects both supply and price. Higher-rarity skins drop less often, which keeps their market value elevated relative to common drops from the same case.

Prices shown are sourced from Steam Community Market and CSFloat, updated every 6 hours. Additional data from Skinport, Buff163, and YouPin. The Steam Community Market charges 15% total fees (5% Steam fee + 10% CS2 game fee), while third-party sites offer lower rates — CSFloat at 2%, Buff163 at 2.5%, and Skinport around 8% — with real-money cashout options. Beyond wear and float, the pattern index (seed 1–999) also affects price for certain finishes like Case Hardened and Fade, where specific patterns can multiply value many times over.
