Wzorzec projektowy Prototyp

Witam, napisałem własną implementację wzorca projektowego: prototyp. Chciałbym się dowiedzieć czy jest ona poprawna.

public enum Handle
{
    Wooden,
    Iron,
    Steel,
    Glass,
    Gold
}

public enum Edge
{
    Iron,
    Steel,
    Glass,
    Gold
}

public enum WeaponType
{
    Sword,
    Mace,
    Axe
}

public class WeaponCreator
{
    private int        cost;
    private Handle     handle;
    private Edge       edge;
    private WeaponType weaponType;

    public WeaponCreator(int cost, Handle handle, Edge edge, WeaponType weaponType)
    {
        this.cost = cost;
        this.handle = handle;
        this.edge = edge;
        this.weaponType = weaponType;
    }

    public Weapon CreateWeapon() => new Weapon(cost, handle, edge, weaponType);
}

public interface ICloneable
{
    object Clone();
}

public class Weapon : ICloneable
{
    public int cost              { get; }
    public Handle handle         { get; }
    public Edge edge             { get; }
    public WeaponType weaponType { get; }

    public Weapon(int cost, Handle handle, Edge edge, WeaponType weaponType)
    {
        this.cost       = cost;
        this.handle     = handle;
        this.edge       = edge;
        this.weaponType = weaponType;
    }

    public object Clone() => MemberwiseClone();
    public override string ToString() => $"Cost: {cost}, Type: {weaponType}, Handle: {handle}, Edge: {edge}";
}

static class Prototyp
{
    public static void Test()
    {
        WeaponCreator weaponCreator = new WeaponCreator(9000, Handle.Glass, Edge.Gold, WeaponType.Sword);
        var clone = weaponCreator.CreateWeapon().Clone();

        Console.WriteLine(clone.ToString());
    }
}
