Flip Knife Case Hardened: Blue Gem Seed Patterns
Flip Knife is one of the grandfather skins in Counter-Strike. Added in 2013 with the now legendary Arms Deal update, it is one of the 5 original knives. Flip Knife as the name suggests “flips”, the animation of opening the knife is a great addition that adds to the charm.
“Flip knives sport a Persian-style back-swept blade with an acute point. While the point itself may be fragile, the overall design of the flip knife's design is surprisingly durable.”
If you’re interested in getting a skin for the Flip Knife, you have plenty of choices. If you really want to set yourself apart from other players in CS2, opting for a Flip Knife Blue Gem could be the perfect choice.

The amount of blue seen on a Case Hardened skin is determined by the knife's seed pattern, which is a number automatically assigned when the skin is unboxed. As a result, some pattern indexes display more blue on the skin, while others feature a playside with more gold coloring.
Determining which seed is the best can be quite difficult, so to make it easier for you, we’ve put together a specific list of the top Blue Gems for the Flip Knife.

Prices
While it's challenging to assign a specific price to a Flip Knife Blue Gem in CS2, it's evident that Blue Gem knives are generally far more expensive than standard Case Hardened versions. Furthermore, knives with a larger amount of blue coloration on the playside tend to be more costly.
If we have a more modest budget, Blue Gems from Tier 1 or 2 will likely be out of reach, but Tier 3 or 4 can still offer some interesting options. Blue Gems are incredible pieces in the entire CS2 skin collection and are definitely unique. Aside from the amount of blue on the blade, it’s also important to consider the value of the float.
When it comes to skins like those, it's important to ask someone, who is experienced and knows the market. It's essential to make a complex research before buying an item like this to make sure we (as a buyer) won't lose a huge amount of money.
How can you acquire a Flip Knife Blue Gem in CS2?
If you're feeling fortunate, you might want to try obtaining this item, by unboxing one directly from a case.
However, the odds are not on your side, so we strongly advise against opening cases.
The easiest way to get a Flip Knife Blue Gem is by buying them on the Steam Community Market, but the 15% fee often makes it pricier. A cheaper option is to buy from trusted third-party marketplaces, where lower transaction fees lead to better prices and a wider selection of skins.
