Dry-tooling vs Adventure Climbing
Dry-tooling is tough on gear, especially ice axes: picks are slotted horizontally, axes levered on underclings, dropped to the ground, etc. All of these stresses can cause invisible damage to the axe, reducing its strength.
Ice axes used for dry-tooling should be reserved exclusively for this activity, and must be carefully inspected before each use: verify the integrity of all elements of the tool, from the pick to the grip.
Most importantly, do not use your dry-tooling gear on adventure climbs (long mountain routes, icefalls...). The fatigue caused by dry-tooling could result in a catastrophic tool failure on a poorly protected route, or on a mulitpitch climb.
