MSR Basecamp Snow Construction Saw Aggressive: Non-linear blade delivers an ultra-efficient cutting pattern, while laser-cut teeth rip snow and ice in both directions, and voids between teeth remove debris from path. Strong: Durable, lightweight 7075 aluminum blade. Rigid: Secure, low-profile locking pin holds reliably through hardpack conditions, and increases stiffness. Compact: Folds its long reach to half its size for ultimate packability and backcountry practicality. Comes in a welded gear-protecting sheath
