The 剃刀松 is a 困難模式, post-世紀之花 魔法武器 that rapid-fires "pine needle" projectiles at high speed (2-4 projectiles per tick) and at high velocity. The projectiles drop off after a modest distance, much like Throwing Knives and the 魔法飛刀, though with slightly longer range. Its projectiles do not pierce multiple 敵怪. The Razorpine has a 5.19%-7.78% chance to be dropped by 常綠尖叫怪 during the 霜月 事件.
Its best 修飾語 is 神話.
- Projectiles spawn more than one 物塊 away from the caster. This allows the caster to effectively shoot through a 1-block thick barrier in any direction when positioned close enough to the barrier. A small fraction of projectiles will spawn far enough away to bypass a 5-block thick barrier. This also allows enemies to avoid some or all of Razorpine's projectiles when they are positioned too close to the caster.
- The Razorpine's projectiles are very similar to the 常綠尖叫怪's Pine Needle projectiles.
- The Razorpine could be considered an upgrade to the 吹葉機, a similar weapon dropped by 世紀之花.
- Before 1.2.3, the Razorpine's best modifier was 神級 because of its previous mana cost of 3. Because of that, it couldn't have any modifiers that affected mana cost.
- 1.2.3：Mana cost increased from 3 to 5.
