Gostei bastante da chave canivete allen KLEIN TOOLS. Trata-se de um jogo de chaves robustas construidas com aço e plástico resistente. Gostei também da bitola enorme que permite trabalhar com parafusos bastante grossos. Resolveu totalmente os meus problemas e por ser chave canivete as chaves encontram-se reunidas. É uma conjunto de chaves brutas ao meu ver e que não quebram fácil. valeu o investimento.
