Morakniv has become the bushcraft or survival knife for many, thanks to their reliability, edge retention, and comparably affordable prices. A Morakniv knife is one you can buy and beat up with little regret, and today both the Kansbol (4.3" blade) and Eldris (2.2" blade) are on sale.
The Kansbol comes in two flavors: with a plain plastic sheath or with a MOLLE Multi-Mount System. The former will set you back about $29 (or $5 off its usual price), but the latter will save you about $20 off its standard price at $40.
As for the Eldris, at $29, it's about $5 off its usual price of $34, but it also comes with a lanyard and fire starter.
Update 6/5/2018: The Morakniv Companion is also on sale now for just over $14, down from its usual price of $17.
