We define a hierarchical clustering method: $\alpha$-unchaining single linkage or $SL(\alpha)$. The input of this algorithm is finite metric space and certain parameter $\alpha$. This method sensitive to the density distribution offers some solution so called chaining effect. also modified version, $SL^*(\alpha)$, treat through points small blocks. study theoretical properties these methods offer background for treatment effects.
