Ok!
Ok, but overprized compared to competitors like Bossil (which is great value!).

Idéal pour les poignées de poêles et de casseroles.

Le seul du site envoyé sous blister et pas d'Inde. Je préfère même si c'est deux fois plus cher. Mes écrous d'axe de roues ne se désserent plus. Prévoir la lampe à souder pour le démontage à 300 degrés celsius.

A must have addition to anyone toolbox. Iconic for it's durability and holding power, this model specifically designed to withstand heat typically as a result of some motor running

Can't buy this anywhere locally. This is great for high-temp uses in gunsmithing (muzzle devices, gas block) and other high-temp needs. I can break it loose with a heat gun and standard wrench if needed.
