	int weaponslot = 0;
	int ent = -1;
	if (weaponslot == 5)
	{
		return Plugin_Handled;
	}
	while ((ent = GetPlayerWeaponSlot(client, weaponslot)) == -1 && weaponslot <= 5)
	{
		weaponslot++;
	}
	while ((ent = GetPlayerWeaponSlot(client, weaponslot)) != -1 && weaponslot <= 5)

This is the stock I made for it

stock void RemoveWeapons(int client, bool leavec4 = true) 
{
		int primary = GetPlayerWeaponSlot(client, 0);
		int secondary = GetPlayerWeaponSlot(client, 1);
		int knife = GetPlayerWeaponSlot(client, 2);
		if (primary > 0) 
		{
			RemovePlayerItem(client, primary);
			RemoveEdict(primary);
		}
		
		if (secondary > 0) 
		{
			RemovePlayerItem(client, secondary);
			RemoveEdict(secondary);
		}
		if (!leavec4)
		{
			int c4medi = GetPlayerWeaponSlot(client, 4);
			if (c4medi > 0) 
			{
				RemovePlayerItem(client, c4medi);
				RemoveEdict(c4medi);
			}
		}
		if (knife == -1)
		{
			GivePlayerItem(client, "weapon_knife");
		}
}

If you want to keep that one, just add

 
int knife = GetPlayerWeaponSlot(client, 2);
if (knife == -1)
{
	GivePlayerItem(client, "weapon_knife");
}

before the end and it should give the knife back.
