I use a pair of secateurs and thick gloves and cut close to the stem. Wear eye protection, the spikes will take an eye out.
When it has finished flowering, cut the flower stem down , leaving the leaves. Maybe not next year but the year after it may flower again. Mine flowered year before last in October, last year nothing, this year it has two spikes.
